Facet temperature mapping of GaAs/AlGaAs quantum cascade lasers by photoluminescence microprobe
Source abstract
Abstract
Abstract The measurement of thermal resistance and facet temperature profile of operating GaAs/AlGaAs quantum cascade lasers (QCLs) as a function of injected current, repetition rate and pulse width is reported. The use of microprobe band-to-band photoluminescence (PL) spectroscopy allows to achieve a spatial resolution
