Extraction of the electron excess temperature in terahertz quantum cascade lasers from laser characteristics

Extraction of the electron excess temperature in terahertz quantum cascade lasers from laser characteristics

We propose a method to extract the upper laser level’s (ULL’s) excess electronic temperature from the analysis of the maximum light output power (P max) and current dynamic range ΔJ d = (J max − J th) of terahertz quantum cascade lasers (THz QCLs). We validated this method, both through simulation a...
