论文摘要
Limaçon形的微台面激光器是有希望的片上光源，其激光阈值低，单向输出。我们对利马形半导体微腔的激光动力学进行了一项实验研究。边缘发射在各种空间和时间尺度上表现出强度波动。它们是由多个动态过程产生的，具有不同的起源，并且发生在不同的时空尺度上。主要过程是两个输出梁之间的替代振荡，其周期短到几纳秒。
Limaçon-shaped microdisk lasers are promising on-chip light sources with low lasing threshold and unidirectional output. We conduct an experimental study on the lasing dynamics of Limaçon-shaped semiconductor microcavities. The edge emission exhibits intensity fluctuations over a wide range of spatial and temporal scales. They result from multiple dynamic processes with different origins and occurring on different spatiotemporal scales. The dominant process is an alternate oscillation between two output beams with a period as short as a few nanoseconds.
