We have investigated the transport properties of In0.53Ga0.47As/AlAs0.56Sb0.44 quantum cascade lasers operating at lambda similar to 4.3 mu m, by means of band-to-band photoluminescence (PL). The evolution of the PL bands with the applied electric field allows a detailed analysis of the injection and emission efficiency. A clear correlation between the device thermal performance and the electron distribution has been found.

Abstract
We have investigated the transport properties of In0.53Ga0.47As/AlAs0.56Sb0.44 quantum cascade lasers operating at lambda similar to 4.3 mu m, by means of band-to-band photoluminescence (PL). The evolution of the PL bands with the applied electric field allows a detailed analysis of the injection and emission efficiency. A clear correlation between the device thermal performance and the electron distribution has been found.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
