Abstract
We observed a very sharp photoluminescence peak from a single GaAs/AlG aAs quantum dot structure by using a microphotoluminescence measuremen t technique. The spectral linewidth was more suppressed by decreasing the excitation laser power, which is mainly due to reduction of the fi lling effect of quantized energy levels. The minimal spectral linewidt h with low excitation laser power was 0.9 meV. (C) 1995 American Insti tute of Physics.
