对1550 nm垂直腔面发射激光器在单脉冲和双脉冲偏振光注入下的偏振开关进行了理论和实验研究。“正常”和“反向”PS，分别实现时，该设备受到单，双光学注入。在双偏振光注入下，观察到反向PS的速度操作增强。此外，“正常”和“反向”PS的最小注入功率要求进行了分析，显示两个调查的情况下显着差异。此外，我们还数值研究了重要的系统参数，如归一化偏置电流，注入场强，和线宽增强因子的最佳操作条件下的两种类型的PS的影响。理论和实验之间的总体良好的协议。
Polarization switching (PS) in 1550-nm VCSELs under single and double pulsed polarized optical injection is investigated experimentally and in theory. "Normal" and "reverse" PS were achieved, respectively, when the device was subject to single and double optical injection. Speed operation enhancement is observed for "reverse" PS under double polarized optical injection. Also, the minimum injection power requirements for both "normal" and "reverse" PS have been analyzed showing significant differences for the two investigated cases. Furthermore, we have also investigated numerically the influence of important system parameters, such as the normalized bias current, the injection field strength, and the linewidth enhancement factor in the optimal operation conditions for both types of PS. Overall good agreement between theory and experiments is found.
