Abstract
There have been much interests in the semiconductor microcavity lasers based on quasi-two-dimensional cavity geometry. Tailoring the cavity boundary shape can induce chaotic ray dynamics, and has a profound impact on the properties of cavity resonances. In the first part of this talk, we will show a wave-chaotic cavity allows many modes lase simultaneously, and the spatial coherence of emission is reduced. The leads to the application of chaotic microcavity lasers as illumination source for speckle-free full-field imaging. In the second part of this talk, we show that lasing instabilities are suppressed in wave-chaotic cavities, due to disruption of filamentation.
