Abstract

Light emitted in directions different from the excitation and reflected beams, generically called secondary emission, has many intriguing aspects. Secondary emission from semiconductor multiple quantum well (QW) excitons after resonant excitation arises from an interplay of QW disorder, photoluminescence, Rayleigh scattered light, and light-coupling effects. In the past decade, much progress has been made on the investigation of Rayleigh scattering after resonant excitation (RRS) from QW excitons^1,2, triggered in part by the improvement of experimental techniques. Although many past studies were done on multiple QW’s, in all cases light-coupling effects were either ignored or ruled out.
