Magnetic Field Induced Redistribution of Exciton-Polariton Density on Confined Modes

Abstract

The inuence of magnetic eld on conned excitonpolariton modes inside a semiconductor microcavity is discussed. The three-dimensional connement for excitonpolaritons is achieved by the mesa structures conning the photonic part of polaritons. We observe a strong increase of the polariton emission intensity and we argue that this eect is due to the change of the oscillator strength of the excitonic component of polaritons and the change of the excitonic content in polariton state as the magnetic eld increases.
