采用平面工艺制作的定向输出微腔半导体激光器是集成光学回路的理想光源。近十几年来,以微盘为代表的回音壁模式(wldspering-gallery mode)微腔激光器引起人们很大的重视。但圆对称的微盘激光器缺乏定向的激光输出,人们往往利用输出波导与微盘实现消逝波耦合或通过改变微盘的对称性来实现定向输出。最近几年,多边形微腔如正三角形、正方形、长方形、六边形等多边形光学微腔 Directional output microcavity semiconductor lasers fabricated using planar technology are ideal sources for integrating optical circuits. For more than a decade, the micro-cavity laser with whispering-gallery mode, which is represented by microdisks, has drawn great attention. However, the circularly symmetric microdisk laser lacks a directional laser output, and the output waveguide and microdisk are often used to achieve the evanescent coupling or the directional output can be achieved by changing the symmetry of the microdisk. In recent years, polygonal microcavities such as regular triangle, square, rectangular, hexagonal and other polygonal optical microcavities
