Cavity-Polariton Effects in II-VI Microcavities

摘要: Semiconductor microcavities are monolithic multilayer heterostructures grown by molecular beam epitaxy. They allow the confinement along growth axis of both photons between Bragg reflectors and excitons in quantum wells. If exciton—photon coupling matrix element is large enough compared to line width, system said be strong regime. In that case a well exciton couples another discrete state: photon mode planar microcavity with same in-plane wave vector, give rise quasi-stationary states named cavity polaritons. this regime, Fermi golden rule does not hold any more optical properties, linear or nonlinear, strongly related polariton features. A review properties CdTe-based operating regime given paper. The strength coupling, dynamic relaxation processes polaniton dispersion curves will discussed, as stimulated emission luminescence.
