摘要

我们利用离子蚀刻技术在外延片上制作了在腔体顶部有“窗口”的准体育场激光二极管，并证明可以观察到直接的激光模式。在载波较差的区域，亮线可以识别。另一方面，在富载流子区域，激光模式被识别为暗线。两条线都很适合扩展的Fox-Li模拟。从这些结果可以理解，激光模式的条件取决于载流子密度。

Beam Mode Observation in Quasi-Stadium Laser Diodes

We fabricated quasi-stadium laser diode which has a 'window' on the top of cavity by ion-etching technique to epitaxial wafer and demonstrated to observe direct lasing mode observation. In the carrier poor region, bright line can recognize. On the other hands, in the rich carrier region, lasing pattern was recognized as dark line. Both lines well fit extended Fox-Li simulation. From these results, it can understand that the lasing pattern condition depend the carrier density.
