Abstract:

We present optical gain and loss spectra measured over a range of carrier densities at low temperature in hexagonal GaN epilayers. We have determined the optical loss directly to be similar to 80 cm(-1). Photoluminescence spectra show that stimulated emission in our samples arises from electron-hole plasma recombination. Time-resolved pump-probe transmission experiments have shown that there is considerable bandgap renormalization for carrier densities at which stimulated emission occurs.
