Theory of Resonant Rayleigh Scattering from Semiconductor Microcavities: Signatures of Disorder

We develop a self-consistent, microscopic theory of coherent resonant secondary emission from semiconductor microcavities in the normal-mode- coupling regime. Our theory provides a quantitative description of the spectral, temporal, and angular properties of the disorder-induced emission component - resonant Rayleigh scattering - and offers an intuitive physical explanation of emission properties.
