Abstract

GaInP quantum well lasers are important for applications such as DVD and photodynamic therapy. The performance of these lasers remains limited by non-radiative and carrier-leakage losses and to design fully optimised devices it is necessary to describe these losses accurately. The paper provides a quantitative analysis of these non-radiative losses through detailed comparison of experimental gain and spontaneous emission spectra with a verified theoretical model. We find that, even in the absence of carrier leakage, there is a substantial contribution to the room temperature threshold current from non-radiative recombination within the wells themselves.
