Abstract :
Summary form only given. Here we show directly that excitonic polaritons dominate the low-temperature optical properties of most GaAs MQW samples of conventional design. These polaritons are the optically active normal modes in which excitons in different QWs exchange photons producing energy splittings in direct analogy with electronically coupled double QWs.
