摘要：
We present a semi-classical theory of exciton-polariton effects in disordered multiple quantum well (MQW) structures in application to GaN/AlGaN MQWs. An original micro-model is proposed that allows to calculate all types of coherent optical spectra of MQWs. We show that GaN/AlGaN MQWs should exhibit pronounced propagation effects in the resonant Rayleigh scattering and the vertical motional narrowing effect in the time-resolved transmission. We predict polariton-induced oscillations in the time-resolved coherent optical spectra of GaN/AlGaN MQWs having a period of the order of hundreds of femtoseconds.
