A polariton laser based on a bulk GaN microcavity

Simulations of polariton relaxation in a bulk GaN microcavity are performed by solving semi-classical Boltzmann equations. The structure which is considered is that of a recently grown microcavity showing strong coupling at 300 K. A kinetic phase diagram is calculated. We show that such a cavity can operate as a low-threshold polariton laser at room temperature.
