Background
Conventionally, in optical communications using an optical transmission medium such as an optical fiber or an optical waveguide, an optical module including a light Emitting element such as a Surface Emitting Laser (for example, a Vertical Cavity Surface Emitting Laser (VCSEL)) or a light receiving element such as a photodetector is used.

Patent document 1 describes a resin lens structure (optical receptacle) including an object plane (first optical plane) and an image plane (second optical plane). In the lens structure described in patent document 1, a light source or a photodetector is fixed to the lens structure so as to face an object plane, and an optical fiber is fixed to the lens structure so as to face an image plane. The lens structure described in patent document 1 guides light emitted from a light source to an end face of an optical fiber, and guides light emitted from the optical fiber to a photodetection device.
As described above, the lens structure described in patent document 1 is used in the field of optical communication. Therefore, the lens structure is assumed to be used in a high-temperature environment or a low-temperature environment. However, since the lens structure described in patent document 1 is made of a resin, it expands in a high-temperature environment and contracts in a low-temperature environment. In this way, the lens structure expands or contracts, and therefore, the positional accuracy of the light source or the photodetection device with respect to the lens structure cannot be maintained, and there is a possibility that the coupling efficiency of light is lowered, and appropriate optical communication cannot be performed. Similarly, the positional accuracy of the optical fiber with respect to the lens structure cannot be maintained, and the coupling efficiency of light may be reduced, thereby failing to perform appropriate optical communication.

Fig. 1A is a cross-sectional view showing an optical module 100 having a photoelectric conversion element package 110 including a photoelectric conversion element 112 and an optical receptacle 140 for optically coupling the photoelectric conversion element 112 with an optical transmission body 150. The cross-sectional view is a cross-sectional view including a first central axis CA1 of the first optical surface 121 and a second central axis CA2 of the second optical surface 122, which will be described later.
As shown in fig. 1A, the optical module 100 includes a photoelectric conversion element package 110 and an optical receptacle 140. In the optical module 100, the photoelectric conversion element 112 of the photoelectric conversion element package 110 and the optical transport 150 are optically coupled through the optical receptacle 140.
The optical module 100 may be a transmitting optical module or a receiving optical module. When the optical module 100 is an optical module for transmission, the optical receptacle 140 guides light emitted from the photoelectric conversion element package 110 to an end surface of the optical transmission body 150. When the optical module 100 is an optical module for reception, the optical receptacle 140 guides light emitted from the end surface of the optical transmission body 150 to the photoelectric conversion element package 110.
The photoelectric conversion element package 110 includes: a case 111, a photoelectric conversion element 112, and a lead 113. A photoelectric conversion element 112 is disposed inside the case 111. The photoelectric conversion element package 110 is fixed to the optical receptacle 140. In the present embodiment, the photoelectric conversion element package 110 is fixed to the optical receptacle 140 so that a part thereof is accommodated in the cylindrical portion 126. More specifically, in the present embodiment, the photoelectric conversion element package 110 is fixed to the cylindrical portion 126 with the adhesive 10.
The photoelectric conversion element 112 is a light emitting element 114 or a light receiving element 115, and is disposed inside the case 111. When the optical module 100 is an optical module for transmission, the photoelectric conversion element 112 is a light emitting element 114. When the optical module 100 is a receiving optical module, the photoelectric conversion element 112 is a light receiving element 115. The light emitting element 114 is, for example, a Vertical Cavity Surface Emitting Laser (VCSEL). The light receiving element 115 is, for example, a photodetector.
One end of the wire 113 is connected to the photoelectric conversion element 112. The lead wires 113 are disposed so as to protrude from the bottom surface of the case 111. The number of the wires 113 is not particularly limited. In the present embodiment, the number of the wires 113 is 3. In the present embodiment, the 3 wires 113 are arranged at equal intervals in the circumferential direction when the photoelectric conversion element package 110 is viewed from below.
When the optical receptacle 140 is disposed between the photoelectric conversion element package 110 and the optical transmission body 150, the photoelectric conversion element package 110 including the light emitting element 114 or the light receiving element 115 is optically coupled to the end surface of the optical transmission body 150. When the optical module 100 is a transmission optical module 100, the optical receptacle 140 receives light emitted from the photoelectric conversion element 112 as the light emitting element 114, and emits the received light to an end surface of the optical transmission body 150. When the optical module 100 is a receiving optical module 100, the optical receptacle 140 receives light emitted from an end surface of the optical transmission body 150 and emits the light to a light receiving surface of the photoelectric conversion element 112 serving as the light receiving element 115.
The kind of the optical transports 150 is not particularly limited. Examples of the kind of the optical transports 150 include optical fibers, optical waveguides. In the present embodiment, the optical transport 150 is an optical fiber. The fiber may be in a single mode or in a multimode mode. In the present embodiment, the optical transmission body 150 is accommodated in the sleeve 151, and the optical transmission body 150 is connected to the optical receptacle 140 through the sleeve 151. The sleeve 151 is a substantially cylindrical member configured to surround the optical transmission body 150. The ferrule 151 is accommodated in the ferrule accommodating portion 129 of the optical receptacle 140, which will be described later, with the optical transmission body 150 accommodated therein.
(Structure of optical receptacle)
As shown in fig. 1A, the optical receptacle 140 has an optical receptacle body 120 and a deformation inhibiting member 130.
The optical receptacle body 120 has a first optical surface 121, a second optical surface 122, a cylindrical portion 126, and a ferrule accommodating portion 129.
The optical receptacle body 120 is a substantially cylindrical optical member. In the present embodiment, the photoelectric conversion element package 110 is fixed to one end of the optical receptacle body 120 via the cylindrical portion 126, and the ferrule 151 accommodating the optical transmission body 150 is fixed to the other end via the ferrule accommodating portion 129.
The optical receptacle 140 is formed using a material having optical transparency to light of a wavelength used in optical communication. Examples of the material of the optical receptacle 140 include Polyetherimide (PEI) such as ULTEM (registered trademark) and a transparent resin such as a cyclic olefin resin. In addition, the light outlet receptacle 140 may be manufactured by integrally molding, for example, by injection molding.
The first optical surface 121 is an optical surface for allowing light emitted from the photoelectric conversion element package 110 (light-emitting element 114) to enter the inside of the optical receptacle 140 or allowing light that has entered the second optical surface 122 and traveled inside the optical receptacle 140 to exit the photoelectric conversion element package 110 (light-receiving element 115). The shape of the first optical surface 121 is not particularly limited. The first optical surface 121 may be a convex lens surface protruding toward the photoelectric conversion element package 110, a concave lens surface recessed from the photoelectric conversion element package 110, or a flat surface. In the present embodiment, the first optical surface 121 is a convex lens surface protruding toward the photoelectric conversion element package 110. The plan view shape of the first optical surface 121 is not particularly limited. The first optical surface 121 may have a circular or elliptical shape in plan view. In the present embodiment, the first optical surface 121 has a circular shape in plan view.
The first central axis CA1 of the first optical surface 121 may or may not be perpendicular to the surface of the photoelectric conversion element 112 (the light-emitting surface of the light-emitting element 114). In the present embodiment, the first central axis CA1 is perpendicular to the surface of the photoelectric conversion element 112 (the light-emitting surface of the light-emitting element 114). In addition, it is preferable that the first central axis CA1 of the first optical surface 121 coincides with the center of the surface of the photoelectric conversion element package 110 (the light emitting surface of the light emitting element 114).
The cylindrical portion 126 is disposed so as to surround the first optical surface 121. The cylindrical portion 126 accommodates at least a part of the photoelectric conversion element package 110 such that the first optical surface 121 faces the photoelectric conversion element 112. In the present embodiment, the cylindrical portion 126 and the photoelectric conversion element package 110 are joined together with the adhesive 10.
In the present embodiment, the cross-sectional shape of the cylindrical portion 126 perpendicular to the first central axis CA1 of the first optical surface 121 is annular.
The second optical surface 122 is an optical surface for allowing light that has entered the first optical surface 121 and traveled inside the optical receptacle 140 to exit to the end surface of the optical transmission body 150 or allowing light that has exited from the end surface of the optical transmission body 150 to enter inside the optical receptacle 140. The shape of the second optical surface 122 is not particularly limited. The second optical surface 122 may be a convex lens surface protruding toward the light transmission body 150, a concave lens surface recessed from the light transmission body 150, or a flat surface. In this embodiment, the second optical surface 122 is a flat surface. The plan view shape of the second optical surface 122 is not particularly limited. The shape of the second optical surface 122 in plan view may be circular or elliptical. In the present embodiment, the second optical surface 122 has a circular shape in plan view.
The second central axis CA2 of the second optical surface 122 may or may not be perpendicular to the end surface of the optical transmitter 150. In the present embodiment, the second central axis CA2 is perpendicular to the end surface of the optical transmission body 150. Preferably, the second central axis CA2 of the second optical surface 122 coincides with the center of the end surface of the optical transmission body 150.
The sleeve accommodating portion 129 accommodates the sleeve 151. By accommodating the ferrule 151 in the ferrule accommodating portion 129, the end portion of the optical transmission body 150 and the second optical surface 122 are arranged at positions opposite to each other. The shape of the sleeve accommodating portion 129 may be complementary to that of the sleeve 151. In the present embodiment, since the sleeve 151 is cylindrical, the sleeve housing portion 129 is cylindrical including a space in which the sleeve 151 can be housed.
The deformation suppressing member 130 is configured to surround the optical receptacle body 120, and is joined to the optical receptacle body 120. In the present embodiment, the deformation suppressing member 130 is an annular member, and is joined to the optical receptacle main body 120 by, for example, bonding, welding, or the like. In the present embodiment, the deformation suppressing member 130 is joined to the cylindrical portion 126 of the optical receptacle main body 120 so as to be along the same. The distortion suppressing member 130 is disposed so as to surround at least a part of the optical path between the first optical surface 121 and the second optical surface 122. In the present embodiment, the entire optical path between the first optical surface 121 and the second optical surface 122 is surrounded by the distortion suppressing member 130. Further, the concave-convex shape may be disposed on the outer peripheral portion of the optical receptacle main body 120 (including the outer peripheral portion of the cylindrical portion 126) as the bonding surface with the deformation inhibiting member 130 to improve the bonding strength.
The deformation suppressing member 130 is made of a material having a smaller linear expansion coefficient than the optical receptacle body 120. Examples of the material having a smaller linear expansion coefficient than the optical receptacle body 120 include metal, resin, and the like. Since the deformation suppressing member 130 has the structure as described above, expansion or contraction of the optical receptacle body 120 due to temperature change can be suppressed, and the position of the first optical surface 121 can be suppressed from being shifted with respect to the photoelectric conversion element 112 of the photoelectric conversion element package 110.
Preferably, the end of the deformation suppressing member 130 on the light transmission body 150 side is located closer to the second optical surface 122 side than the edge of the first optical surface 121. Further, it is more preferable that the end of the deformation suppressing member 130 on the light transmission body 150 side is positioned closer to the light transmission body 150 side than the second optical surface 122. Further, the end of the deformation suppressing member 130 on the photoelectric conversion element package 110 side is preferably located closer to the photoelectric conversion element package 110 side than the top of the first optical surface 121. By positioning both end portions of the deformation suppressing member 130 as described above, the deformation suppressing member 130 is positioned so as to surround the first optical surface 121, and thus the positional deviation of the first optical surface 121 can be more reliably suppressed.
(suppression of positional deviation of optical surface at high and low temperatures)
Fig. 1B and 1C are diagrams illustrating a case where the distortion suppressing member 130 suppresses the occurrence of positional deviation of the center of the first optical surface 121 at high temperature and low temperature, respectively.
As shown in fig. 1B, at high temperature, a force in a direction away from the first central axis CA1 of the first optical surface 121 and the second central axis CA2 of the second optical surface 122 acts on the first optical surface 121 and the second optical surface 122 due to expansion of the optical receptacle body 120, but the presence of the deformation suppressing member 130 suppresses expansion of the optical receptacle body 120.
On the other hand, as shown in fig. 1C, at low temperatures, forces in the directions of the first central axis CA1 and the second central axis CA2 of the first optical surface 121 act on the first optical surface 121 and the second optical surface 122 due to contraction of the optical receptacle body 120, but the presence of the deformation suppressing member 130 suppresses contraction of the optical receptacle body 120.
Accordingly, the deformation suppressing member 130 suppresses the occurrence of the deviation in the position of the center of the first optical surface 121 at both high and low temperatures.
(Effect)
According to the optical receptacle of embodiment 1, even when the temperature around the optical receptacle changes, the positional deviation of the first optical surface can be suppressed, and the decrease in the light coupling efficiency can be suppressed.
[ embodiment 2]
Fig. 2 is a diagram showing an optical module 200 according to embodiment 2. The optical module 200 of embodiment 2 differs from the optical module 100 of embodiment 1 in that the optical receptacle 240 does not have the cylindrical portion 126. The optical module according to embodiment 2 is different from the optical module 100 according to embodiment 1 in that one end of the deformation inhibiting member 230 is configured to surround the optical receptacle main body 220, and the other end is configured to accommodate at least a part of the photoelectric conversion element package 110 so that the first optical surface 121 faces the photoelectric conversion element 112.
The deformation suppressing member 230 may be one member or may be composed of two members. In the case where the deformation suppressing member 230 is formed of two members, the deformation suppressing member 230 is formed of a first deformation suppressing member configured to surround the optical receptacle main body 220 and a second deformation suppressing member configured to house at least a part of the photoelectric conversion element package 110 such that the first optical surface 121 faces the photoelectric conversion element 112. The end portion of the first deformation suppressing member on the first optical surface 121 side and the end portion of the second deformation suppressing member on the first optical surface 121 side may be joined by, for example, welding.
In the optical module 200 according to embodiment 2, the same components as those of the optical module 100 according to embodiment 1 are denoted by the same reference numerals, and descriptions thereof are omitted.
The deformation suppressing member 230 may be bonded to the optical receptacle main body 220 by bonding, welding, or the like. In the present embodiment, the deformation suppressing member 230 is bonded to the optical receptacle main body 220 by the adhesive 10.
The deformation inhibiting member 230 may have various configurations as described below, in the same manner as the deformation inhibiting member 130, except that it is configured to accommodate at least a part of the photoelectric conversion element package 110.
That is, the deformation suppressing member 230 may be made of a material having a smaller linear expansion coefficient than the optical receptacle main body 220 and configured to surround the optical receptacle main body 220. At least a part of the optical path between the first optical surface 121 and the second optical surface 122 may be surrounded by the distortion suppressing member 230.
Further, one end of the deformation inhibiting member 230 is preferably positioned closer to the second optical surface 122 side than the edge of the first optical surface 121.
(Effect)
According to the optical receptacle of embodiment 2, even if the ambient temperature of the optical receptacle changes, the positional deviation of the first optical surface can be suppressed, and the decrease in the light coupling efficiency can be suppressed. In addition, the photoelectric conversion element package and the optical receptacle body can be fixed together by the deformation suppressing member 230.
[ embodiment 3]
Fig. 3A is a diagram illustrating an optical module 300 according to embodiment 3. The optical module 300 according to embodiment 3 differs from the optical module 200 according to embodiment 2 in that the optical receptacle body 320 includes a protector 326 for the first optical surface 121, which is disposed around the first optical surface 121.
In the optical module 300 according to embodiment 3, the same components as those of the optical module 200 according to embodiment 2 are denoted by the same reference numerals, and descriptions thereof are omitted.
As described above, in the optical module according to embodiment 3, the optical receptacle main body 320 includes the protection portion 326. Thereby protecting the first optical surface 121 and suppressing the first optical surface 121 from being damaged. The protective portion 326 is disposed so as to surround the first optical surface 121. The protection portion 326 may be cylindrical or convex. When the protection portion 326 is a convex portion, two or more convex portions exist. The end of the protection portion 326 on the photoelectric conversion element package 110 side is located closer to the photoelectric conversion element package 110 side than the top of the first optical surface 121.
(Effect)
According to the optical receptacle of embodiment 3, even if the ambient temperature of the optical receptacle changes, the positional deviation of the first optical surface can be suppressed, and the decrease in the light coupling efficiency can be suppressed. The first optical surface 121 can be protected by the protection portion 326.
[ embodiment 4]
Fig. 3B is a diagram showing the optical module 400 according to embodiment 4. In the optical module 400, the optical receptacle main body 420 has the groove 127 disposed around the first optical surface 121. In the optical module 400, the same components as those of the optical module 100 are denoted by the same reference numerals, and descriptions thereof are omitted.
The groove 127 may be provided with nothing or the deformation inhibitor 128. In the present embodiment, as shown in fig. 3B, the deformation inhibiting material 128 is disposed in the groove portion 127.
Preferably, the depth of the groove portion 127 is greater than the width of the groove portion 127. Since the groove portions 127 have a depth to such an extent that the first optical surface 121 is not affected by expansion or contraction of the surrounding material, the position of the first optical surface 121 is further suppressed from being displaced due to a temperature change. In the present embodiment, the bottom of the groove 127 is located closer to the optical transmission body 150 than the second optical surface 122.
The deformation suppressing material 128 has a linear expansion coefficient smaller than that of the optical receptacle main body 420. Examples of the deformation inhibiting material 128 include (a cured product of) an adhesive. Since the deformation suppressing material 128 is a material having a smaller linear expansion coefficient than the optical receptacle main body 420, expansion and contraction of the optical receptacle are suppressed, and positional deviation of the first optical surface 121 is further suppressed.
(Effect)
According to the optical receptacle of embodiment 4, even if the ambient temperature of the optical receptacle changes, the positional deviation of the first optical surface can be suppressed, and the decrease in the light coupling efficiency can be suppressed.

The utility model discloses an optical receptacle and optical module are useful to the optical communication who uses optical transmission body.
