Abstract
The invention discloses a silicon workbench which is used for bearing an optical fiber. The silicon workbench comprises a body, a groove and an optical element, wherein the groove and the optical element are arranged on the body; the groove is used for accurately aligning the optical fiber with the optical element; the body comprises a first surface and a second surface which are opposite to each other, as well as a third surface and a fourth surface which are opposite to each other; the groove sinks towards the second surface from the first surface, and extends towards the fourth surface from the third surface; the optical element is arranged in the position, on the fourth surface, corresponding to the groove; the groove adopts a square structure and comprises a first part and a second part which are connected with each other; one end, far away from the second part, of the first part is a plane; the second part takes the shape of a horn.
Description
Technical field
The present invention relates to a kind of silicon worktable.
Background technology
In the situation that frequency range requirement is more and more higher, optical circuit board (optical PCB), the joints of optical fibre will become the major way that does not solve high-speed transfer.The joints of optical fibre always are the large difficult point of one in making in the assembling of optical fiber, especially using the connector of silicon worktable (silicon bench) as photoelectricity transmission interface, need to be in miniature vee-cut assembling optical fiber, only, existing V-shaped groove is quite difficult on aiming at, thereby yield is affected.
Summary of the invention
In view of this, be necessary to provide a kind of assembling easily and aim at accurate silicon worktable.
A kind of silicon worktable, be used for bearing fiber, described silicon worktable comprises a body and is arranged on groove and the optical element on described body, described groove is used for making described optical fiber accurately to aim at optical element, described body has relative first surface and second surface and the 3rd relative surface and the 4th surface, described groove is extended to described the 4th surface to described second surface depression and by described the 3rd surface by described first surface, described optical element is positioned at the position of described the 4th corresponding described groove in surface, described groove is square structure and comprises connected first part and the second part, described first part is plane away from one end of described the second part, described the second part is horn shape.
Compared to prior art, the silicon worktable of the present embodiment partly imports optical fiber in groove because employing has second of horn opening, thereby makes importing comparatively easy, and in addition, square groove easily makes accurate alignment between optical fiber and optical element.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the silicon worktable 10 that the embodiment of the present invention provides is used for bearing fiber 20, has groove 12 and optical element 13 on silicon worktable 10.
Groove 12 fixed fibers 20 and be used to determine optical fiber 20 and optical element 13 between there is high-precision contraposition.
Optical element 13 can be lens, light emitting diode or photodiode.
The number of groove 12 and optical element 13 and distribution mode are determined by number and the distribution mode of the optical fiber 20 arranging on silicon worktable 10.
Silicon worktable 10 has a body being roughly square 11, and body 11 has relative first surface 111 and second surface 112 and relative the 113 and the 4th surface 114, the 3rd surface.Groove 12 is used the semiconductor processing technology of knowing to be formed on body 11, for example, and etching mode.Groove 12 is extended to the 4th surface 114 to second surface 112 depressions and by the 3rd surface 113 by first surface 111, and groove 12 ends near the 4th surperficial 114 places.
Certainly, in other embodiment, the shape and size of body 11 according to actual needs, can have different size.
The cross sectional shape of groove 12 in vertical length direction is square, and groove 12 comprises first part 121 and the second part 122.The length of first part 121 is greater than the length of the second part 122.First part 121 122 is connected with the second part, first part 121 away from second partly 122(near the 4th surface 114) one end be square planar.
The second part 122 comprises that the width of narrow end 1221 and wide end 1222, the second parts 122 is increased to wide end 1222 gradually by narrow end 1221, so that the second part 122 flare shapes.Narrow end 1221 is connected with first part 121, and wide end 1222 is connected with the external world.
Optical element 13 is positioned on the 4th surface 114, and corresponding first part 121, aims at light signal is coupled between optical fiber 20 and optical element 13 when optical fiber 20 is assembled in groove 12 with optical element 13.
When optical fiber 20 is assembled into silicon worktable 10, after wide end 1222 importings of the second part 122 are also constantly stretched in groove 12, row is fixing again.
Second part 122 due to employing with horn opening imports optical fiber 20 in groove 12, thereby makes importing comparatively easy, and in addition, square groove 12 easily makes accurate alignment between optical fiber 20 and optical element 13.
Be understandable that, those skilled in the art also can do other variation etc. in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
