Electric Field Enhancement of the Rabi Splitting in a Superlattice-Microcavity System

Abstract

We have observed a large coupling between the photonic mode of a microcavity and Stark-localized excitons from a superlattice embedded in it. The coupling is signi cantly stronger than in comparable microcavities that contain quantum 11 wells solely at the antinodes. The large density of exciton states in a superlattice and their large binding energy, once they are con ned by an electric eld, explain this enhancement.
