Enhancement of spin coherence using Q-factor engineering in semiconductor microdisc lasers

Abstract
Semiconductor microcavities offer unique means of controlling light–matter interactions in confined geometries, resulting in a wide range of applications in optical communications and inspiring proposals for quantum information processing and computational schemes. Studies of spin dynamics in microcavities, a new and promising research field, have revealed effects such as polarization beats, stimulated spin scattering and giant Faraday rotation.
