Abstract

The dependences of the radiation intensity in various circular polarizations from injection surface-emitting lasers with a vertical chiral microcavity on the excitation current value were experimentally investigated. A sharp increase of the circular polarization degree of the laser emission from small values ∼5% to values >70% was observed at a current exceeding the threshold value. Considering the nonlinear optical properties of laser resonators, model calculations were performed, and the calculation results are in good agreement with the experiment.

注入半导体激光器圆偏振发射产生阈值的实验研究

实验研究了垂直手性微腔注入面发射激光器在不同圆偏振方向的辐射强度与激发电流值的关系。在超过阈值的电流下，观察到激光发射的圆极化度从小值~ 5%急剧增加到>；70%。考虑到激光谐振腔的非线性光学特性，进行了模型计算，计算结果与实验结果吻合较好。
