Abstract
Confocal scanning laser microscopy was used for the first time to obtain the submicron-scale photoluminescence (PL) of InGaN/GaN single quantum wells (SQWs). We found island-shaped spatial inhomogeneities of both PL intensities and spectra as small as 100-200 nm. The spatial resolution of the obtained PL images was much smaller than the diffusion length of carriers in active layers at room temperature.
