Description of the drawings
Fig. 1 is the side structure schematic view of the utility model.
Fig. 2 is the overlooking structure diagram of the utility model.
Fig. 3 is the light-emitting surface schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of double angle fiber arrays in end face include substrate 1, on the side of the substrate 1
Several tactic V-grooves 11 are provided with, an optical fiber 12, the V-groove are both provided in any one described V-groove 11
Bonding fiber agent is provided in 11；The top of the V-groove 11 is provided with cover board 2, and the substrate 1 and cover board 2 pass through pressing
Mode is fixed.
The beneficial effects of the utility model are, reduce overall dimensions, are conducive to promote light path coupling efficiency, improve transmission matter
Amount.The technological process of production of the utility model is as follows：Optical fiber 12 is put into sequence in the conduit of V-groove 11 first, then
Optical fiber 12, V-groove 11 and cover board 2 are assembled using the agent of optical fiber fixed bonding, and ensure V-groove 11 and lid in assembling process
2 end face of plate is staggered a fragment position, on the one hand realizes that part fiber at the tail portion platform of V-groove 11 is exposed in the outside of cover board 2,
And ensure that cover board 2 can cover most of optical fiber 12 on V-groove 11；Then use fixation pressure by substrate 1 and cover board 2
It compresses, ensures optical fiber 12 and the both sides of V-groove 11 and the lower contact of cover board 2, so that it is guaranteed that all optical fiber 12 are in same water
In plane；Then solidification is exposed to optical fiber fixed bonding agent using ultraviolet lamp.After solidification, the naked light on V-groove
Point bare fibre Protection glue 3 protects optical fiber 12 at fibre.After glue is fully cured, by abrasive polishing process appropriate by light
The angle that the end face of V-groove 11, optical fiber 12 and cover board 2 and horizontal direction are formed all is ground into 98 °, ground by fibre array end face
Make slicer cutting technique or laser processing technology after the completion of mill, the end face of cover board 2 be processed into from the horizontal by 90 °,
Control working depth is paid attention in process, prevents damage optical fiber 12, light is caused to reveal.
The angle Selection that the utility model forms the end face of V-groove 11, optical fiber 12 and cover board 2 and horizontal direction at 98 °,
Purpose is according to industry general level, and return loss value can improve the requirement for meeting optical integrated device to 60dB or more, with routine
90 ° of return loss are compared in 50dB, and return loss value is substantially improved, and performance is more excellent；The end face of cover board 2 and horizontal direction are formed
Angle Selection is at 90 °, it is therefore an objective to reduce cover board extension elongation, be calculated according to cover sheet thickness 1mm, reduction size is 1/tan
(θ), θ are the polishing angle of V slots and optical fiber, are calculated by 98 °, then reduce 0.14mm.
In addition, the core of the utility model can be different away from d, optical fiber 12 and the polishing angle of V-groove can be changed, product
Size also can be changed according to product usage scenario.Therefore the expansibility of the utility model is more conducive to product
It promotes and applies.The description and the appended drawings are regarded in an illustrative, rather than a restrictive simultaneously.
