半导体微盘激光器中的光反馈和耦合问题

Optical feedback and the coupling problem in semiconductor microdisk lasers

Jens U. Nockel

摘要:

发光微腔的尺寸越小,理解腔边界对光学模式分布的影响就变得越重要。传统的激光物理方法,如近轴近似,在这里讨论的许多更奇特的腔设计中变得不适用。微盘、柱和环形状的腔可以在各种各样的增益介质中产生低的激光阈值:量子阱、线甚至点,以及量子级联超晶格和GAN。概述的实验和理论状态,特别强调光提取问题。

英文摘要:

The smaller the size of a light-emitting microcavity, the more important it becomes to understand the effects of the cavity boundary on the optical mode profile. Conventional methods of laser physics, such as the paraxial approximation, become inapplicable in many of the more exotic cavity designs to be discussed here. Cavities in the shape of microdisks, pillars and rings can yield low lasing thresholds in a wide variety of gain media: quantum wells, wires and even dots, as well as quantum cascade superlattices and GaN. An overview of the experimental and theoretical status is provided, with special emphasis on the light extraction problem.
