PHOTONIC GENERATION AND STEERING OF COHERENT VORTEX BEAMS

摘要

A bound states in the continuum (BIC) surface emitting laser includes a light emitter configured to generate BIC light waves. The laser also includes an array of holes with equal radii extending through the light emitter such that light emitted by the light emitter upon receipt of power is emitted as a coherent vortex beam at an angle to a surface normal of the light emitter that is determined at least in part by the radius of the holes in the array.
