摘要

光子晶体非常适合于光场的控制和光的传播特性。作为一种重要的应用，基于线缺陷构成的光子晶体平板波导(PC-WGs)的超紧凑超快光学集成电路(OIC)[1,2]。PC-WG对激光激光也很有吸引力，因为在布里渊区(BZ)边缘附近很小的群速度会增强辐射场与物质之间的相互作用。实际上，已经从嵌入多模W3型(三行缺失线缺陷)PC-WG中的光泵浦inas量子点(InAs-QDs)中观察到了激光光谱[3]。在本研究中，我们观察了激光在单模W1型(单行缺失线缺陷)的InAs-QDs PC-WG中的作用。

InAs quantum-dots laser utilizing GaAs W1 type photonic-crystal slab line-defect waveguide

Photonic crystals are very suitable for controlling radiation field and propagation characterization of light. As an important application, it is ultra compact and ultrafast optical integrated circuits (OIC) based on photonic crystals slab waveguides (PC-WGs) composing of the line-defects [1, 2]. The PC-WG is also attractive for laser lasing, because very small group velocity of near the Brillouin zone (BZ) edge should enhance interactions between the radiation field and matter. Indeed, the lasing spectrum has been observed from optically pumped InAs-quantum dots (InAs-QDs) embedded in PC-WG of the multimode W3 type (three rows missing line-defect) [3]. In the present study, we observe laser action in InAs-QDs PC-WG of the single-mode W1 type (single row missing line-defect).
