Abstract

A periodic multiple quantum well GaAs/AlGaAs structure was designed, grown and characterized in order to reveal resonant features in optical spectra when the Bragg resonance was tuned to the first or second quantum state of the heavy-hole exciton-polaritons in the quantum wells. We observed a super-radiant optical mode formed by the quantum well excitons under double resonance condition, i.e. when the exciton-polariton and Bragg resonances are met at the same frequency. It is manifested in a strong and wide reflection and electroreflection band.
