Embodiment
Below in conjunction with embodiment the present invention is described in further detail:
The present invention realizes by following steps:
1, the preliminary work that is coupled and aligned: be installed on the waveguide frame after earlier waveguide being cleaned up; Optical fiber is cleaned up, an end is installed on the accurate adjustment rack of incident end again, and the other end connects light source;
2, observe the position of incident end optical fiber and waveguide by microscopic observation system, and pass through the depth of parallelism and the end face interval of computer instruction manual adjustment optical fiber and waveguide;
3, open LASER Light Source and tentatively judge the situation that is coupled and aligned of incident end optical fiber and waveguide, good logical light effect when realizing optical fiber and waveguide butt joint according to the output system analysis;
4, assembling waveguide output terminal fiber array (FA) adopts step 2 that the waveguide output terminal is connected with fiber array again and tentatively adjusts to suitable position; Be connected to then on two sniffing interfaces of binary channels power meter;
5, start the position that the luminous power search utility is adjusted waveguide output terminal and fiber array automatically, the optical power value maximum that the waveguide exit end is received, and the optical power value of two sampling channels should equate as far as possible;
6, after the optical power value of waveguide output terminal fiber array reaches maximum and equates as far as possible, carry out a glue job again;
7, repeating step 6, seek the luminous power maximal value that waveguide output terminal fiber array receives once more, aim at the optimum coupling of fiber array with waveguide behind the guarantee point glue, and with its curing, carry out subsequent operation again, finish encapsulation.
In the process that is coupled and aligned of the present invention, all output channels of PLC shunt all will accurately be aimed at, because the manufacturing process of waveguide chip and fiber array (FA) has guaranteed each interchannel relative position, so only need the PLC shunt is aimed at simultaneously with first passage and last passage of FA, just can guarantee that other passages have also realized aligning, can reduce the complexity of encapsulation like this.Most important in the superincumbent encapsulation operation, technical difficulty is the highest is exactly the operation that is coupled and aligned, it comprises just being in harmonious proportion accurately aims at two steps.Wherein the purpose of initial adjustment is to make the logical light that waveguide can be good; Accurately the purpose of aiming at is the accurate location of finishing the optimum power Coupling point, and it is realized by the peaked program of search luminous power.The butt joint optical waveguide needs 6 degree of freedom; 3 translations (X, Y, Z) and 3 rotations (α, β, g) will make the waveguide device of encapsulation functional, and then the translation precision of Dui Zhuning should be controlled at below 0.5 micron, and rotation precision should be higher than 0.05 degree.
The design of coarse adjustment accurately among the present invention:
Based on physioptial reflection law, light signal propagates into another dielectric surface that can reflect, and reflection and refraction effect can take place from a surface, wherein incident ray and reflection ray spatially are symmetrical, utilize such character, can observe and judge the situation of incident medium face conversely.Planar optical waveguide input end coarse adjustment design is set out according to this law exactly, and combined high precision optical alignment equipment is accurately judged the space articulation quality of input end and planar optical waveguide.
