摘要：

The experiment and simulation on reduction of postweld shift caused by laser welding on a butterfly-type laser module package employing Nd:YAG laser welding and separated dual clips are demonstrated in this study. Based on the measurement of fiber tip position, the direction and quantity of fiber alignment shift caused by laser welding joining are quantitatively measured, and the postweld shift during laser welding also can be compensated by separated dual clips with pre-compensation. The experimental results also show that the coupling efficiency can be regained up to 79%-95% of optimum coupling power The simulation results show the regained coupling efficiency of 81%-96% and also match quite well the experimental results in trends.
