Abstract

We demonstrate theoretically and experimentally that a specifically designed microcavity driven in the optical parametric oscillation regime exhibits lighthouse-like emission, that is, an emission focused around a single direction. Remarkably, the emission direction of this microlighthouse is continuously controlled by the linear polarization of the incident laser, and angular beam steering over 360° is demonstrated. Theoretically, this effect arises from the interplay between the nonlinear optical response of microcavity exciton-polaritons, the difference in the subcavities forming the microcavity, and the rotational invariance of the device.
