Optical gain reduction caused by nonrelevant subbands in narrow-period terahertz quantum cascade laser designs
The recent designs of terahertz quantum cascade lasers usually employ the short periodic length and also the tall barriers for high-temperature operation. In this work, the effect of high-energy lying non-relevant subbands is studied based on nonequilibrium Green’s function formalisms model, demonst...
