实验研究了小面积垂直腔面发射激光器在最小阈值附近的偏振选择与注入电流和衬底温度的关系。从低到高的频率基本空间模式的偏振切换被证明。有效双折射率在过渡区出现最小值。动态过渡态的观察暗示了非线性效应的相关性。比较圣米格-冯-莫洛尼模型的预测的基础上的相位-振幅耦合。
Polarization selection in small-area vertical-cavity surface-emitting lasers is studied experimentally in dependence of injection current and substrate temperature in the vicinity of the minimum threshold condition. Polarization switching from the low to the high frequency fundamental spatial mode is demonstrated. The effective birefringence displays a minimum in the transition region. The observation of dynamical transition states hints to the relevance of nonlinear effects. A comparison to the predictions of the San Miguel–Feng–Moloney model based on phase-amplitude coupling is given.
