Abstract:

Numerical simulation of time-resolved light reflection from GaNAlGaN single and multi-quantum wells MQWs revealed a pronounced vertical motional narrowing effect. This effect consists in reduction of the in homogeneous broadening of the exciton peaks and increase of the decay-time of the time-resolved reflection due to the averaging of the vertical disorder in the structure by extended exciton-polariton modes. The theory predicts pronounced oscillations in the time-resolved reflection of MQWs resulting from the interference of exciton-polariton modes in the structure.
