Exciton-light coupling in quantum wells: from motional narrowing to superradiance

We show numerically that spatial delocalization of excition-polariton states in multiple quantum wells leads to efficient narrowing of exciton resonances with respect to the single-quantum-well (QW) case. This is a manifestation of a motional narrowing effect, i.e., averaging of short-range potentia...
