随着数据模块速率的提升，例如，数据模块速率从100G升级到400G，数据模块中的电路元件日益增加，进而留给光器件的封装空间越来越小。With the increase of the data module rate, for example, the data module rate is upgraded from 100G to 400G, the circuit elements in the data module are increasing, and the packaging space for optical devices becomes smaller and smaller.
在现有的100G光器件中，采用四路稀疏波分复用器(Coarse Wavelength Division Multiplexer，CWDM)，可以将4个中心波长复用到一根光纤上进行传输。在光信号发射过程中，通常直接将光波导组件的端面与光纤组件的端面进行直接耦合，存在封装尺寸大的问题。In the existing 100G optical devices, a four-channel sparse wavelength division multiplexer (CWDM) is used to multiplex the four central wavelengths onto one optical fiber for transmission. In the process of optical signal transmission, the end face of the optical waveguide component and the end face of the optical fiber component are usually directly coupled directly, which has the problem of large package size.

图1为本公开实施例提出的一种光耦合组件的示意图。如图1所示，本公开实施例提出一种光耦合组件，该光耦合组件包括：FIG. 1 is a schematic diagram of an optical coupling component proposed by an embodiment of the disclosure. As shown in FIG. 1, an embodiment of the present disclosure provides an optical coupling component, and the optical coupling component includes:
光波导组件10，具有第一耦合端面，第一耦合端面用于供光信号输出；The optical waveguide assembly 10 has a first coupling end surface, and the first coupling end surface is used for outputting optical signals;

光纤组件30，具有与反射组件相对设置的第二耦合端面，并与光波导组件位于反射组件的同一侧，其中，第二耦合端面，用于供从反射组件反射的光信号进入到光纤组件所包含的光纤内。The optical fiber assembly 30 has a second coupling end face disposed opposite to the reflective assembly and is located on the same side of the reflective assembly as the optical waveguide assembly. The second coupling end face is used for the optical signal reflected from the reflective assembly to enter the optical fiber assembly. The included fiber.
本公开实施例中，光耦合组件用于将光波导组件10的输出的光信号，输出至光纤组件30所包含的光纤内。In the embodiment of the present disclosure, the optical coupling component is used to output the output optical signal of the optical waveguide component 10 to the optical fiber included in the optical fiber component 30.
需要说明的是，光波导组件10具有第一耦合端面，光纤组件30具有第二耦合端面，该第一耦合端面和第二耦合端面均与反射组件20相对设置，且均设置在反射组件20的同一侧。It should be noted that the optical waveguide assembly 10 has a first coupling end face, and the optical fiber assembly 30 has a second coupling end face. Both the first coupling end face and the second coupling end face are arranged opposite to the reflection assembly 20, and both are arranged on the reflection assembly 20. Same side.
示例性地，如图2所示，光纤组件30在光波导组件10上，该第一耦合端面101和第二耦合端面301相对于反射组件20平齐放置在反射组件20的同一侧。并且，光波导组件10和光纤组件30的接触面与第一耦合端面101垂直，光波导组件10和光纤组件30的接触面与第二耦合端面301垂直。Exemplarily, as shown in FIG. 2, the optical fiber assembly 30 is on the optical waveguide assembly 10, and the first coupling end face 101 and the second coupling end face 301 are placed flush with the reflecting assembly 20 on the same side of the reflecting assembly 20. In addition, the contact surface of the optical waveguide component 10 and the optical fiber component 30 is perpendicular to the first coupling end surface 101, and the contact surface of the optical waveguide component 10 and the optical fiber component 30 is perpendicular to the second coupling end surface 301.
本公开实施例中，光纤组件30包括定位槽，该定位槽用于将光纤固定放置在槽内。例如，该定位槽位的形状包括三角形状，本公开实施例这里不作限制。In the embodiment of the present disclosure, the optical fiber assembly 30 includes a positioning groove for fixing the optical fiber in the groove. For example, the shape of the positioning slot includes a triangular shape, which is not limited in the embodiment of the present disclosure.
如图2所示，第一耦合端面101设置为矩形形状，第二耦合端面301设置为圆形形状。As shown in FIG. 2, the first coupling end surface 101 is set in a rectangular shape, and the second coupling end surface 301 is set in a circular shape.
当然，第一耦合端面101和第二耦合端面301还可以设置为其他的形状，例如，第一耦合端面101可以设置为圆形形状，第二耦合端面301可 以设置为矩形形状，本公开实施例这里不作限制。Of course, the first coupling end surface 101 and the second coupling end surface 301 can also be set in other shapes. For example, the first coupling end surface 101 can be set in a circular shape, and the second coupling end surface 301 can be set in a rectangular shape. There is no restriction here.
在光信号传输的过程中，第一耦合端面101的输出的光信号，经过反射组件20反射，反射后的光信号通过第二耦合端面301进入到光纤组件30所包含的光纤内。In the process of optical signal transmission, the output optical signal of the first coupling end face 101 is reflected by the reflection component 20, and the reflected optical signal enters the optical fiber contained in the optical fiber assembly 30 through the second coupling end face 301.
可以理解的是，本公开实施例的光波导组件10和光纤组件30放置在反射组件20的同一侧，通过反射组件20能够将光波导组件10第一耦合端面101输出的光信号转折180度聚焦到光波导组件30上的第二耦合端面301。也就是说，本公开实施例的光波导组件10和光纤组件30采用立体的方式对光信号进行耦合，能够有效减少光耦合组件的封装长度。It is understandable that the optical waveguide component 10 and the optical fiber component 30 of the embodiment of the present disclosure are placed on the same side of the reflective component 20, and the optical signal output by the first coupling end surface 101 of the optical waveguide component 10 can be turned 180 degrees to focus by the reflective component 20 To the second coupling end surface 301 on the optical waveguide assembly 30. In other words, the optical waveguide assembly 10 and the optical fiber assembly 30 of the embodiment of the present disclosure couple optical signals in a three-dimensional manner, which can effectively reduce the package length of the optical coupling assembly.
在一种实施例中，如图3所示，反射组件20具有第一光学面201和第二光学面202，第一光学面201和第二光学面202分别位于反射组件20的相对两侧；In an embodiment, as shown in FIG. 3, the reflective component 20 has a first optical surface 201 and a second optical surface 202, and the first optical surface 201 and the second optical surface 202 are respectively located on opposite sides of the reflective component 20;
反射组件20，用于对从第一光学面201进入的光信号进行准直；并通过第二光学面202对准直后的光信号进行反射，反射后的光信号经过第一光学面201输出至第二耦合端面301。The reflective component 20 is used to collimate the optical signal entering from the first optical surface 201; and reflect the aligned optical signal through the second optical surface 202, and the reflected optical signal is output through the first optical surface 201 To the second coupling end surface 301.
可以理解的是，反射组件20对光信号进行准直，能够使得光信号以最大的效率输出至第二耦合端面301。It can be understood that the reflection component 20 collimates the optical signal, so that the optical signal can be output to the second coupling end surface 301 with the greatest efficiency.
需要说明的是，第一光学面201用于供光信号进入或者输出。也就是说，第一光学面201可以作为透射面。It should be noted that the first optical surface 201 is used for entering or outputting optical signals. In other words, the first optical surface 201 may serve as a transmission surface.
第二光学面202用于反射通过第一光学面201进入的光信号，使得光信号从第一光学面201输出至第二耦合端面301。也就是说，第二光学面201可以作为反射面。The second optical surface 202 is used to reflect the optical signal entering through the first optical surface 201 so that the optical signal is output from the first optical surface 201 to the second coupling end surface 301. In other words, the second optical surface 201 may serve as a reflective surface.
在一种实施例中，第一光学面201为镀有增透膜的光学面；第二光学面202为镀有反射膜的光学面。In one embodiment, the first optical surface 201 is an optical surface coated with an antireflection film; the second optical surface 202 is an optical surface coated with a reflective film.
需要说明的是，增透膜用于增加光信号的透过率；反射膜用于增加光信 号的反射率。It should be noted that the antireflection film is used to increase the transmittance of the optical signal; the reflective film is used to increase the reflectance of the optical signal.
可以理解的是，镀有增透膜的第一光学面能够最大程度的让第一耦合端面输出的光信号透过第一光学面，提高了光信号的透过率，进而能够提高光信号的传输效率，降低损耗。镀有反射膜的第二光学面能够最大程度的将透过第一光学面的光信号反射至第二耦合端面，提高了光信号的反射率，进而能够提高光信号的传输效率，降低损耗。It is understandable that the first optical surface coated with an antireflection coating can allow the optical signal output by the first coupling end surface to pass through the first optical surface to the greatest extent, thereby increasing the transmittance of the optical signal, and thereby improving the optical signal Transmission efficiency, reduce loss. The second optical surface coated with a reflective film can reflect the optical signal transmitted through the first optical surface to the second coupling end surface to the greatest extent, thereby improving the reflectivity of the optical signal, thereby improving the transmission efficiency of the optical signal and reducing the loss.
本公开实施例中，通过第一耦合端面101输出的光信号，可以从第一光学面201进入到反射组件20，再通过第二光学面202反射，反射后的光信号再从第一光学面201输出至第二耦合端面301。In the embodiment of the present disclosure, the optical signal output through the first coupling end surface 101 can enter the reflective assembly 20 from the first optical surface 201, and then be reflected by the second optical surface 202, and the reflected optical signal can then be reflected from the first optical surface. 201 is output to the second coupling end surface 301.
在一种实施例中，反射组件20的焦平面处于第一光学面上；In an embodiment, the focal plane of the reflective component 20 is on the first optical surface;
或者，反射组件20的焦平面，位于反射组件20内，并与第一光学面201之间的距离在第一距离范围内；Alternatively, the focal plane of the reflective component 20 is located in the reflective component 20, and the distance from the first optical surface 201 is within the first distance range;
或者，反射组件20的焦平面，位于反射组件20外，并与第一光学面201之间的距离在第二距离范围内。Alternatively, the focal plane of the reflective component 20 is located outside the reflective component 20 and the distance from the first optical surface 201 is within the second distance range.
本公开实施例中，反射组件20的焦平面可以设置在第一光学面201附近，还可以设置在第一光学面201上。In the embodiment of the present disclosure, the focal plane of the reflective assembly 20 may be set near the first optical surface 201 or may be set on the first optical surface 201.

可以理解的是，将反射组件的焦平面设置在第一光学面上，能够提高光信号的耦合效率。并且，反射组件的焦平面与第一光学面之间的距离设置在100微米范围内，能够减少反射组件的焦平面与光纤组件之间的距离，以及反射组件的焦平面与第一耦合端面的距离，降低了耦合损耗。It can be understood that setting the focal plane of the reflective component on the first optical surface can improve the coupling efficiency of the optical signal. In addition, the distance between the focal plane of the reflective component and the first optical surface is set in the range of 100 microns, which can reduce the distance between the focal plane of the reflective component and the optical fiber component, and the distance between the focal plane of the reflective component and the first coupling end surface. Distance reduces the coupling loss.
在一种实施例中，第一耦合端面101与第二耦合端面301相对于反射组件20互为物像。In an embodiment, the first coupling end surface 101 and the second coupling end surface 301 are object images with respect to the reflective component 20.
本公开实施例中，当第一耦合端面101与第二耦合端面301相对于反 射组件20互为物像时，光耦合组件的光路为：光波导组件10输出的光信号透过第一光学面201后被反射组件准直；准直后的光信号经过第二光学面202反射，反射后的光信号被聚焦到第二耦合端面301，进而能够进入到光纤组件30所包含的光纤内。In the embodiment of the present disclosure, when the first coupling end surface 101 and the second coupling end surface 301 are object images with respect to the reflective component 20, the optical path of the optical coupling component is: the optical signal output by the optical waveguide component 10 passes through the first optical surface After 201, it is collimated by the reflection component; the collimated optical signal is reflected by the second optical surface 202, and the reflected optical signal is focused on the second coupling end surface 301, and then can enter the optical fiber contained in the optical fiber component 30.
可以理解的是，当第一耦合端面101与第二耦合端面301相对于反射组件20互为物像时，能够使得通过第二光学面202反射的光信号聚焦到第二耦合端面301，进而提高了耦合效率。It can be understood that when the first coupling end surface 101 and the second coupling end surface 301 are object images with respect to the reflective component 20, the optical signal reflected by the second optical surface 202 can be focused to the second coupling end surface 301, thereby improving了 Coupling efficiency.
需要说明的是，可以调整反射组件20的位置，使得第一耦合端面101与第二耦合端面301互为物像。在反射组件20相对于第一耦合端面101和第二耦合端面301之间的位置调试完毕后，可以将反射组件20的位置进行固定，以实现光耦合组件的光路固定。It should be noted that the position of the reflective component 20 can be adjusted so that the first coupling end surface 101 and the second coupling end surface 301 are object images to each other. After the adjustment of the position of the reflective component 20 relative to the first coupling end surface 101 and the second coupling end surface 301 is completed, the position of the reflective component 20 can be fixed to realize the fixation of the optical path of the optical coupling component.

示例性地，第一光学面201与第一耦合端面101之间的固定连接方式以及第一光学面201与第二耦合端面301之间的固定连接方式，均包括但不限于粘接固定。也就是说，可以通过在固定连接的位置涂抹胶水，以实现粘接固定。Exemplarily, the fixed connection mode between the first optical surface 201 and the first coupling end surface 101 and the fixed connection mode between the first optical surface 201 and the second coupling end surface 301 include, but are not limited to, adhesive fixation. In other words, glue can be applied to the fixed connection position to achieve adhesive fixation.
在一种实施例中，如图2所示，第一耦合端面101和第二耦合端面301具有相同的抛光角度，且第一耦合端面101和第二耦合端面301位于同一平面上。In an embodiment, as shown in FIG. 2, the first coupling end surface 101 and the second coupling end surface 301 have the same polishing angle, and the first coupling end surface 101 and the second coupling end surface 301 are located on the same plane.
