We achieved low-threshold ultra-violet lasing in optically pumped GaN/AlGaN separate confinement heterostructures over a wide temperature range. Lasing modes of a single microcavity were examined from 20 to 300 K and gain mechanisms were compared to

Optically pumped stimulated emission (SE) and time-resolved photoluminescence (TRPL) of InGaN/(In)GaN multiple quantum wells (MQWs) grown by low-pressure metalorganic chemical vapor deposition (MOCVD) were systemically studied as a function of well a

The non-equilibrium carrier dynamics in GaN epilayer for carrier densities ranging from 4 X 1017 to 1019 cm-3 at 10 K was studied by femtosecond pump-probe transmission spectroscopy. Spectral hole burning was initially peaked roughly at the excitatio

We report on the effect of the position of the Si delta-doped layer within a GaN barrier layer on the optical properties of a InGaN∕GaN single quantum well (SQW) with an emission wavelength of 374nm. When the Si delta-doped layer was very close to
