我们通过光泵浦演示了在具有 InAs/GaAs 自组装量子点的光子晶体纳米腔中以 1.3 μm 进行室温连续波激光操作。通过分析耦合率方程和实验光-光特性图，我们评估激光器的自发发射耦合因子接近0.22。量子点系统中的体积效应导致的三维载流子限制和低透明载流子密度在室温下的连续激光操作以及高品质因数光子晶体纳米腔中发挥着重要作用。 (c) 2006 年美国光学学会。
We demonstrate room temperature continuous-wave laser operation at 1.3 mu m in a photonic crystal nanocavity with InAs/GaAs self-assembled quantum dots by optical pumping. By analyzing a coupled rate equation and the experimental light-light characteristic plot, we evaluate the spontaneous emission coupling factor of the laser to be similar to 0.22. Three-dimensional carrier confinement and a low transparent carrier density due to volume effect in a quantum dot system play important roles in the cw laser operation at room temperature as well as a high quality factor photonic crystal nanocavity.
