Abstract

Photoluminescence and reflectivity spectra of a high-quality InGaAs/GaAs quantum well structure reveal a series of ultranarrow peaks attributed to the quantum confined exciton states. The intensity of these peaks decreases as a function of temperature, while the linewidths demonstrate a complex and peculiar behavior. At low pumping the widths of all peaks remain quite narrow (
