摘要

研究了外延晶圆上方形腔、六边形腔、空心方形腔和空心六边形腔的激光谐振特性。在中空的多角形半导体腔中，可以观察到由光在内外边界的全反射形成的导模。研究发现，在空心六边形腔中，导模的腔损失比在空心方形腔中要小得多。关键词:窃窃廊模式，导流模式，空腔

Various Polygonal Semiconductor Lasers

Lasing characteristics of resonance modes were investigated in square, hexagon, hollow square, and hollow hexagonal cavities made on an epi-wafer. In hollow polygonal semiconductor cavities, guided modes were observed in which the modes were formed by total reflections of light at both (outer and inner) boundaries. The cavity loss of guided modes in a hollow hexagonal cavity was found to be considerably reduced compared to that in a hollow square cavity. Keywords-whispering gallery mode, guided mode, hollow cavity
