Abstract

We present continuous wave laser emission in a photonic crystal microcavity operating at 1.5 microm at room temperature. The structures have been fabricated in an InP slab including a single layer of self-assembled InAs/InP quantum wires (QWrs) as active material. Laser emission in air suspended membranes with thresholds of effective optical pump power of 22 microW and quality factors up to 55000 have been measured.

摘要

我们展示了在室温下工作于1.5微米波长的光子晶体微腔中的连续波激光发射。这些结构是在一个InP平板中制造的，其中包含单层自组装InAs/InP量子线（QWrs）作为有源材料。已测量了空气悬浮膜中的激光发射，其有效光泵浦功率阈值为22微瓦，品质因数高达55000。
