摘要

为了提高埋入光纤挠性基板光电互联系统中激光束与光纤之间的耦合效率，设计了一种可分离式的高效光电耦合模块。对耦合模块的结构尺寸进行了设计，并运用Matlab软件分析了激光束经过45全反射镜时的能流变化情况；针对芯径为62.5 m、数值孔径为0.25的多模光纤，利用Zemax软件仿真模拟光纤耦合系统，并用正交下降法优化耦合系统结构，将单路波长为1 310 nm、输出功率为1 W的垂直腔面激光束耦合进光纤。分析结果表明，耦合效率与轴向偏差、角向偏差成中心对称分布，当制造误差最大时，耦合效率达到79.37%，耦合损耗为1.00 dB。该光电耦合模块具有较高的定位误差，最高耦合效率可达85.35%，最低耦合损耗为0.69 dB。

Abstract

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 m 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.
