Abstract
The invention relates to a novel light path coupling fiber array. The novel light path coupling fiber array comprises a substrate, a cover plate and a strip-shaped optical fiber. The novel light path coupling optical fiber array is characterized in that a concave groove with high evenness is formed in the substrate, a bare fiber part of the strip-shaped optical fiber is arranged in the concave groove, and the cover plate, the strip-shaped optical fiber and the substrate are fixedly bonded through glue. Compared with the prior art, the novel light path coupling optical fiber array has the advantages that, under the condition that accuracy of light guiding is ensured, the production cost of the optical fiber array is reduced greatly.
Description
Technical field
The present invention relates to fiber optic communication field and sensory field of optic fibre, more particularly, the present invention relates to be convenient to bare fibre and optical device and carry out light path coupled fiber array.
Background technology
In the conventional fiber array, in order to locate the spacing between each bare fibre accurately, convenient and other optical devices are coupled, and the light path coupled fiber array of prior art mainly contains following two kinds of versions:
V grooved fiber array: use V-type groove substrate (see figure 1), ribbon fiber, cover plate to make fiber array.Method for making is roughly: by the pedestal of V-type groove as bearing fiber, optical fiber is placed in the V-type groove, and pushes down bare fibre with cover plate, fill glue in substrate and cover plate, bare fibre is by fully accurately fixing behind the solidified glue.
Plate fiber array: use plate substrate (see figure 2), ribbon fiber, cover plate three parts to form.Method for making is roughly: by the pedestal of plate substrate as bearing fiber, the use special fixtures on plate pedestal, is used fixedly bare fibre of glue with fiber orientation in substrate and cover plate, and bare fibre is fully accurately fixed behind the solidified glue.
In some cases, because the variation of the flatness of the loading end of many bare fibres of plate base plate carrying can reach or surpass 10 μ m, in any case the size of light guide path accurately is set, still can not guarantee accurately leaded light, therefore cause the loss of transmission light excessive, perhaps can't transmit.Therefore the plate substrate that uses in the plate fiber array needs high flatness, and this has caused the raising of cost, and the flatness that perhaps needs to use special method to overcome the bearing optical fiber face is to the influence of light transmission.
Many bare fibres are arranged the influence of precision for the bearing optical fiber surface evenness that solves plate substrate, a kind of method of making fiber array is proposed, need not the high plate substrate of flatness, but just high precision is arranged each bare fibre (seeing Chinese patent application public publication 200610025404.1).But this kind method need be used multiple anchor clamps, has influenced the production efficiency of fiber array, and the fiber array of the method making does not use the yield height of the fiber array of V-type groove substrate manufacture.
The job operation of the high precision V-type groove substrate that uses in the V flute profile fiber array is closely ripe, and by the precision optical machinery process equipment, its equipment common procurement is in country such as the Japan of precision processing technology prosperity.The equipment price costliness, service equipment is costly, causes the selling at exorbitant prices of V groove, thereby causes the selling at exorbitant prices of fiber array.
Though V flute profile fiber array technology is ripe, but because when processing V-type groove, the angle of V groove, the degree of depth etc. are had strict technical requirement, so to cutter and process equipment strict requirement is arranged, cause the production efficiency of V grooved fiber array low, price is very expensive.Use plate substrate need overcome the problem of the flatness of loading end, use the plate substrate of high-flatness, there is not advantage with respect to V-type groove substrate on the price, use the less demanding plate substrate of flatness, need use special anchor clamps in process of production, and production process is more, has influenced the yield of production efficiency and product.
Summary of the invention
For solving the problems of the technologies described above, the objective of the invention is: a kind of novel light path coupled fiber array is provided, the shape of substrate is improved, greatly reduce difficulty and the technical requirement of processing, make production cost reduce in a large number, and can guarantee accurate leaded light.
The technical scheme that patent of the present invention adopts is: comprise substrate, cover plate and ribbon fiber, it is characterized in that substrate is provided with concave groove, the bare fibre of ribbon fiber is placed in the concave groove, and cover plate is fixedlyed connected with ribbon fiber and substrate.
Press such scheme, the flatness error of described substrate concave groove bottom is not more than 1um.
Press such scheme, described substrate and or cover plate adopting quartz glass, Pyrex, single crystal silicon material in any one make.
Press such scheme, the fibre core of every optical fiber that is placed on the ribbon fiber in the substrate concave groove is equidistant.
Press such scheme, the fibre core that is placed on every optical fiber of the ribbon fiber in the substrate concave groove equates to the distance bottom the substrate concave groove.
Press such scheme, adopt glue bonding between the bare fibre of described cover plate and ribbon fiber and the substrate.
Press such scheme, described glue adopts any in heat-curable glue, ultra-violet curing glue or the two curing glue.
The invention has the beneficial effects as follows: (1) concave groove substrate is than the easier processing of V-type groove substrate, only need smooth the getting final product of bottom processing with concave groove, processing and accuracy detection are simply more than the V-type groove, thereby production cost is reduced greatly, thereby have reduced the cost of fiber array; (2) because the bearing optical fiber face of concave groove substrate passes through machining, and precision can reach 1 μ m, so can guarantee the bearing accuracy of many bare fibres, guarantee the coupling performance of fiber array; (3) than the fiber array that uses the V-type groove to make, it is big that the space between concave groove substrate and the cover plate becomes, and diminishes with the contacted material area of glue, makes the glue fill process become simpler, can effectively avoid bubble, and bright line etc. are unusual; (4) because the concave groove substrate only need guarantee the flatness of bearing optical fiber face, need guarantee the flatness on plane, whole bearing optical fiber face place on working (finishing) area, to descend significantly with respect to plate substrate, reduced manufacturing cost, improved the yield of substrate simultaneously.(5) compare the not plate substrate by processing of bearing optical fiber face, though the concave groove substrate slightly increases on cost, but when cleaning material, need the area of emphasis cleaning greatly to reduce, improve cleaning efficiency, in the process of accurately arranging bare fibre, need not to overcome the flatness of bearing optical fiber face to the influence of many bare fibres arrangement precision, so use the concave groove substrate to have superiority more at integrated cost.
The invention belongs to a kind of half-way house that adopts V-type groove substrate and adopt plate substrate to make fiber array in sum, reduced the cost of the starting material substrate of fiber array, take into account performance and the production efficiency of product simultaneously.
