摘要：
In order to improve the coupling efficiency between the laser beams and the fiber embedded in the optical fiber interconnection system of the flexible substrate, a detachable and efficient photoelectric coupling module was designed in this paper. First of all, the structure size of the coupling module was analyzed, and the energy flow change of the laser beam was simulated with Matlab software after passing through the 45° total reflection mirror. In addition, Zemax software was used to simulate the fiber coupling system and optimize the structure of the coupling system with the orthogonal descent method, in regard to the multi-mode optical fiber with a core diameter of 62.5 μm and a numerical aperture of 0.25. Furthermore, the vertical cavity surface emitting laser beams with a wavelength of 1 310 nm and an output power of 1 W were coupled into the fiber. The analysis results showed that the coupling efficiency was axially symmetrical with axial deviation and angular deviation. When the manufacture deviation was maximum, the coupling efficiency reached 79.37% and the coupling loss was 1.00 dB. Therefore, the module had a high position deviation, the highest coupling efficiency can reach up to 85.35% and the lowest coupling loss was 0.69 dB. © 2019, Science Press. All right reserved.
