| 摘 要： | 基于垂直腔表面发射激光器(VCSELs)的自旋反转模型, 研究了互注入VCSELs系统中参数连续变化所引起的多次偏振转换(PS)特性. 研究结果表明: 连续改变互注入强度ξ、两个互注入VCSELs中一个激光器的激射频率以及同时连续改变两个激光器的激射频率, 均可产生多次的PS. 详细分析了上述三种参数连续变化所引起的多次PS的特性, 并讨论了耦合延时时间对多次PS特性的影响.

| Abstract: | Based on the spin-flip model, the characteristics of multiple polarization switching (PS) in mutually-coupled vertical-cavity surface emitting laser (VCSEL) are investigated by continuously changing some important parameters. The simulated results show that multiple PS can be generated through continuously varying the mutually-coupled strength, the oscillation frequency of one VCSEL or the oscillation frequencies of two VCSELs. The characteristics of multiple PS under the above three scenarios are analyzed, and the influence of the delay-coupled time on the performance of multiple PS is also discussed. |
