Lasing emission patterns from Monza-shaped semiconductor microcavities

We fabricated Monza-shaped semiconductor microcavity lasers and evaluated their far-field characteristics. From the ray dynamical point of view, the Monza-shaped cavity belongs to a special class of fully chaotic cavities; its phase space is decomposed into two independent chaotic components, which yield two different emission patterns. In the present paper, we discuss which ensemble of ray trajectories (i.e., phase space measure) can reproduce far-field emission patterns observed in experiments.
