Abstract

Semiconductor quantum microcavities are structures in which quantum wells are grown inside an optical cavity. The light field is confined by two Bragg mirrors, and the two dimensional quantum wells create confined exciton states. In an appropriately designd sample the photons in the cavity and the quantum well exciton can couple together creating a quasi particle called a cavity polariton. Fisher et al [1] have observed unexpected narrowing of the polariton spectral lines near cavity mode-exciton resonance.
