摘　　要：针对高速光发射组件金属光口(receptacle)与调节环穿透焊后光路耦合效率明显降低这个工艺难点,采用基于有限元热-结构耦合理论分析方法,建立焊接模型并计算出焊后偏移量。根据计算结果用实验数据对比分析加焊前预补偿与不加焊前预补偿的耦合效率:与不加补偿相比,加补偿后的耦合效率平均提高了50%。这一结果对高速光器件尤其是多通道集成光器件的封装开发以及生产都具有一定的指导意义。After the laser welding of the receptacle and the sleeve,the coupling efficiency will fall obviously. In order to study this problem,based on finite element thermal theory and structural coupling theory,laser welding model was developed and the post-weld shift was calculated. According to the experiment,compared to the devices without compensation,the coupling efficiency has increased 50% after the compensation of the PWS. This result has a certain guiding significance for the packaging development and production of high-speed optical devices,especially multi-channel integrated optical devices.
