Abstract
The utility model discloses an optical element connecting device, which comprises a plurality of connecting elements installed between two optical elements or between an optical element and a fixing susceptor, and the connecting elements adopt meniscoid surface cooperation or wedge angle surface cooperation. Since the connecting elements of the utility model adopt the meniscoid surface cooperation or the wedge angle surface cooperation, as long as the connecting elements matched with the meniscoid surface have relative rotation, the direction of the optical elements is adjusted easily; as long as the connecting elements matched with the wedge angle surface have relative slip, the interstices among the connecting elements are eliminated or adjusted. The adjustment of relative position between optical bodies and the connection of small interstices are realized through adopting temperature mutual compensating material among the connecting elements and adopting a gluing and welding way. The constant distance or small distance variation among the connecting elements is guaranteed, causing the utility model to have good position and temperature stability.
Description
Technical field
The utility model relates to a kind of optics and optical-fibre communications optical passive component of relating to, and particularly relates to a kind of coupling arrangement of optical element.
Background technology
At optical field, because very high to the mechanical parts assembly precision, it is can high-precision requirement to satisfy it that normal employing is placed on the adjustable mechanical part with the part optical element.The mode of all elements is fixed in less employing, and in optical communication optical passive component field, needs its element integral body enough little, so the difficult structure that adjustable apparatus is arranged that adopts.In the past some years, optical passive component encapsulates one of generally employing mode and is: the scolding tin welding utilizes the irreversible deformation of metal to come the element of welding is carried out minute adjustment and correction simultaneously; Another platform is to utilize the lens combination adjustable feature directly to coat enough thin glue on the logical light face of optical element to glue together, and carries out small adjusting simultaneously in the glue fixation procedure, realizes required accuracy requirement.These two platforms have good and bad separately point: for jig, advantage is that light path does not have glue, adapt to the device wide ranges, its shortcoming is to go single-piece to make by the skilled labor, also can adopt the robotization mode to make, this brings instability to product quality, and the device temperature of welding production stability is not as the element of end face gummed platform making simultaneously.Have its advantage of gummed platform of glue to be to end face, temperature performance is good, can partly realize automatic assembling, and its shortcoming end face just has glue, and light injury threshold is lower, and its suitable device scope is less on the other hand.
At above-mentioned two platform weakness, a lot of in recent years companies propose end face is not had the glue glued adhesion platform, as USP 6,142,678; US6,347,170B1,131; US 6,282, and 339; US6,246,813B1,131; Pub NO:US 2003/0044115A1, Pub NO:2003/0063853A1; US6,400,867B1, Chinese patent CN254185FY.These end faces gummed platforms can be divided into two classes, and as regulating element one class mutually, another kind is that elementary cell is adjusted to a class with the collimating apparatus with optical fiber head and lenticule.
Visible Fig. 1 (sees USP 6,540,411B1) to first kind typical structure
A kind of typical end face glues together platform as shown in Figure 1, and it comprises optical fiber cable 101,102,111, sleeve pipe 103,105,109,110, kapillary 104,112, lens 106,108, diaphragm 107.This structural advantage is to obtain better temperature performance, its weakness seemingly be can be movable element too many, it is limited to be suitable for device.
Shown in another kind of typical structure Fig. 2 (US6,400,867B1), it comprises the concavo-convex ball surface 206,207 of optical fiber cable 201,202, sleeve pipe 205,208, double optical fiber head 203, lens 204, WDM diaphragm 209, sleeve pipe.This design attempts can guarantee to be connected with less clearance by concavo-convex ball surface that diaphragm 209 enters another optical fiber with the reflected light reflection simultaneously.This structure is feasible from principle, but also seems too coarse from technical standpoint, and practicality is relatively poor.Lens 204 are in sleeve pipe 205,208 inside, this collimation device is made and surperficial wiping brings big difficulty, another problem is to slide mutually to regulate by sphere to be difficult to operation, can only separate the back adjusting remerges together, be difficult to so again the optimum position is transferred in the gap, another problem is that this scheme implementation can run into more difficulty if diaphragm 209 is when also having range accuracy to require.
The utility model content
The coupling arrangement that the purpose of this utility model is to provide a kind of position and temperature stability is good, the gap between the web member is easy to the optical element eliminating and adjust.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of coupling arrangement of optical passive component, and it comprises and is installed between two optical elements or the two or more at least web members between optical element and the fixed pedestal; Adopt male and fomale(M﹠F) to cooperate between described two or more at least web member or the cooperation of angle of wedge face.
It is that concavo-convex sphere cooperates that described male and fomale(M﹠F) cooperates.
Described web member is made of first web member and second web member; Adopt concavo-convex sphere to cooperate between described first web member and second web member.
Described web member is made of first web member and second web member; Adopt angle of wedge face to cooperate between described first web member and second web member.
Described web member is made of first web member, second web member and the 3rd web member; Adopt concavo-convex sphere to cooperate between described first web member and second web member, adopt angle of wedge face to cooperate between second web member and the 3rd web member.
Described web member is made of first web member, second web member, the 3rd web member and the 4th web member; Adopt concavo-convex sphere to cooperate between the cooperation of described first web member and second web member, between second web member and the 3rd web member mutually against, adopt angle of wedge face to cooperate between the 3rd web member and the 4th web member.
Between described optical element and the web member, can adopt glue or welding manner to realize being connected of microclearance between web member and the web member.
After adopting such scheme, owing to adopt male and fomale(M﹠F) to cooperate or the cooperation of angle of wedge face between a plurality of web members between the utility model setting and two optical elements or optical element and the fixed pedestal, the web member that male and fomale(M﹠F) cooperates as long as relatively rotate, just can be easy to adjust the direction of optical element; The web member that angle of wedge face cooperates, as long as slide relatively, just can eliminate or adjust the gap between the web member, and by between web member, adopting the temperature material of compensation mutually, can guarantee then between the web member that distance remains unchanged or changes lessly, makes it have position and temperature stability preferably.
