Paper Abstract

We present a detailed experimental study of photoluminescence upconversion in GaAs quantum wells over a wide temperature range. The dependence of the upconversion on the well width is discussed and the conversion efficiency is determined as a function of laser detuning. The best results are achieved when the laser detuning is comparable to the thermal energy of the system, ▵E≈2kBT.
