Description

Optical fiber array block
The present invention relates on being coupled, fibre-optic optical fiber array block is set, more particularly, relate to the optical fiber array block that makes the downsizing of light wave guide card with integrated optical device I/O optical waveguide.
Be used for making optical fiber attached to the optical fiber array block on the optical waveguide device processed, optical fibre ring generally uses the piece of band V-shaped groove to fix.Here, the interfibrous distance of adjacent optical is corresponding with band coating fiber optics diameter, i.e. 250 μ m.In this case, fibre-optic coating is removed; Subsequently optical fiber is installed in the clad that has 125 μ m diameters in the V-shaped groove.
In general, in optical fiber array block, because distance is 250 μ m between optical fiber, thereby the distance that is coupled between fibre-optic I/O waveguide is necessary for 250 μ m.Optical waveguide device is microscler, and promptly length breadth ratio is 1000: 1.In order to reduce the bending loses in the waveguide, waveguide must have less conversion on than conduction orientation at Width.The waveguide transitions angle is usually less than 1 °.Therefore, in order to make the I/O optical waveguide with 250 μ m gaps, outside optical waveguide device function of tonic chord part, the curvilinear waveguides zone that is used to connect its function of tonic chord part optical waveguide and I/O waveguide is necessary.Owing to added curvilinear waveguides, the length of optical waveguide device is along with input sharply increases with the increase of output.
For addressing the above problem, a target of the present invention provides an optical fiber array block, wherein optical fiber does not have the gap and arranges, and makes that the distance between the optical fiber of optical fiber array block is made and the corresponding 125 μ m of optical fibre packages coating diameter, thereby reduces the size of light wave guide card.
Therefore, for realizing above-mentioned target, provide an optical fiber array block here, it is composed as follows: one contains fibre-optic fiber array, and wherein the coating of each optical fiber predetermined length is removed; A matrix that is used for installing fiber array; One is used for fixing the optical fiber fixed block that fiber array is removed coating layer portion, and is used for fixing and is placed on the epoxy resin that the matrix coupling part is removed the fiber array of coating.Matrix wherein is by the front portion, rear portion and connecting portion branch are formed, the front portion of matrix and the I/O of optical waveguide device are optical waveguide coupled and have a fibre-optic groove that coating is removed in an arrangement, its rear portion has one to settle the fibre-optic groove of band coating, and the coupling part is used to connect the front portion and the rear portion of matrix, it has a ramp structure makes its wide variety be in from anterior width in the scope toward rear portion width transition, and removes the optical fiber of coating in this part arrangement.By with reference to the accompanying drawings the most preferred embodiment here being described in detail, above-mentioned target of the present invention and advantage will be clearer and more definite.
Figure 1A, 1B and 1C are the planimetric map according to optical fiber array block of the present invention, side view and front view.
With reference now to accompanying drawing, the present invention is described in detail.Figure 1A, 1B and 1C are the planimetric maps according to optical fiber array block of the present invention, and side view and front view are comprising fibre-optic matrix 120, optical fiber 100 and 130, optical fiber fixed block 110 and epoxy resin 140 are installed.
Matrix 120 is pieces that are used for installing fiber array, and comprises front portion 102, rear portion 106 and coupling part 104.The I/O of front portion 102 and optical waveguide device (not shown) is optical waveguide coupled and have an arrangement to remove the fibre-optic groove of coating.This groove is processed to and is removed the width of the corresponding 125 μ m of coating diameter of the optical fiber product of coating.Its rear portion 106 has one to place the fibre-optic groove of band coating, and this groove is processed to and the diameter of band coating optical fiber product and the fibre-optic quantity corresponding width that will place.104 anterior 102 of its coupling parts and rear portion 106 couple together and have ramp structure, and promptly its wide variety is in from anterior 102 width in the scope of rear portion 106 width transition.The optical fiber that is removed coating is placed in coupling part 104.In other words, when optical fiber is installed on the matrix 120, anterior 102 and rear portion 106 between the space lentamente from corresponding to 125 μ m of anterior 102 width to 250 μ m bendings corresponding to rear portion 106 width.The length of coupling part 104 is appropriately regulated according to being placed fibre-optic quantity, makes the massive losses that brings because of bending can not produce having on the outermost layer optical fiber of maximum curvature.In general, the optical fiber of installation is many more, and chamfered region must be also long more.
Be used to settle the most preferred embodiment of fibre-optic matrix 120 according to processing, use a kind of silicon crystal substrate.SiO 2Or Si 3N 4With the bar paten form from wherein forming membranaceous SiO 2Or Si 3N 4Silicon wafer substrate (100) lining remove, in KOH solution, carry out wet etching then.In such a way, the front portion of matrix, rear portion and be in the front portion and the rear portion between chamfered region can form simultaneously.As another kind of substitute mode, be used to install fibre-optic matrix and can use mechanical means or casting processing.
Optical fiber 100 and 130 is installed in 104 li of the front portion 102 of matrix 120 and coupling parts with the band coating state, and be used in 106 li at the rear portion of matrix 120 with the decoating state, for the purpose of easy to install and use, it is effective utilizing the strip optical fiber.
The optical fiber fixed block processed make it to be enough to push down the optical fiber that is installed in matrix 120 front portions 102, so that can fix optical fiber.For this purpose, optical fiber fixed block 110 preferred design become the structure have with matrix 120 out-phase complementations.According to most preferred embodiment, optical fiber fixed block 110 uses the processing of wet corrosion method.As an alternative, the optical fiber fixed block can use mechanical means or casting to form.
Epoxy resin 140 is fixed the fiber arrays that are removed coating of location in matrix 120 coupling parts 104, and its thickness 106 becomes littler from anterior 102 to the rear portion.Epoxy resin 140 is removed except that the optical fiber of layer except location in coupling part 104, also can fix the predetermined length band coating optical fiber of location in rear portion 106.
Optical fiber array block is according to optical fiber 100 and 130 being installed on the matrix 120, being coated with epoxy resin and pushing down with optical fiber fixed block 110 on them and make that the fixing order of the optical fiber of location is processed in matrix 120 front portions 102.Then, the anterior section of optical fiber array block polished in case afterwards with the optical waveguide device waveguide sheet with less loss on I/O optical waveguide coupled.
According to the present invention, the length that is used for obtaining the necessary bent lightguide of the distance zone of optical waveguide device waveguide sheet I/O waveguide can reduce by fibre-optic spacing is reduced by half, promptly reduce to 125 μ m, thereby reduced the size of optical waveguide device greatly from 250 μ m.
