摘要

本文演示了二维气桥型gaas光子晶体板中嵌入线缺陷波导的光泵浦InAs量子点在室温下的激光操作。发现在没有法布里-珀罗反射镜的情况下发生激光，并且在样品边缘也没有任何反射。在带边缘的分布反馈机制与一个逐渐消失的小群速度负责目前的激光。

Room temperature operation of InAs-quantum-dot laser utilizing GaAs-photonic-crystal-slab-based line-defect waveguide with optical pump

Room temperature operation of lasing from optically-pumped InAs quantum dots embedded in a line defect waveguide in a two-dimensional air-bridge type GaAs-photonic crystal slab is demonstrated. The lasing is found to occur without Fabry-Perot mirrors, and also without any reflection at the sample edge. A distributed feedback mechanism at the band edge with a vanishingly-small group-velocity is responsible for the present lasing.
