Abstract

In this paper we present coherent nonlinear opticaJ studies of a composite exciton - cavity system. By observing coherent oscillations in spectrally resolved transient four-wave mixing (FWM), we show, for the first time to our knowledge, the excitation of a coherent superposition of the two normal modes of the composite system, and we demonstrate directly in the time domain the coherent energy exchange between the excitan and the cavity.¹ Deep coherent oscillations with a period that varies with the normal-mode splitting persist even when detuning between the cavity and the excitan is much greater than the exciton-cavity coupling rate.
