Method and system for assembly and calibration of polarization-maintaining fibers in co-packaged optics

A system for assembly and calibration of polarization-maintaining fibers in co-packaged optics, applicable to calibrating the angles of a plurality of polarization-maintaining fibers in a plurality of V-shaped grooves arranged side by side on the substrate and each polarization-maintaining fiber having a bare fiber segment and a cladding segment, the system comprising:

• a machine platform, provided with at least one low-frequency vibrator;
• a carrier platform, provided on the machine platform, able to attach to and fix the substrate, and having a transparent stopper facing the substrate;
• a carrier, installed above the machine platform through the low-frequency vibrator, provided with side-by-side accommodating grooves, wherein the bare fiber segment is located in the V-shaped groove, and the cladding segment is located in the accommodating groove, and the transparent stopper limits the length of the bare fiber segment extending out of the V-shaped groove;
• a first pressing assembly, provided on the machine platform, comprising a first driving device, a cantilever, and a plurality of probe units provided on the cantilever;
• the first driving device able to drive the cantilever to rise and fall, and the probe able to rise and fall independently, able to exert pressure on the corresponding bare fiber segment when lowered;
• a second pressing assembly, located on the machine platform, comprising a second driving device and a pressing part, the second driving device able to raise drive the pressing part to rise and fall, and able to exert pressure on the cladding segment;
• and
• an optical inspection lens set, provided on the machine platform and located correspondingly to the substrate, and being used for photographing the end-face of the bare fiber segment.
