Microscopic analysis on optical gain of terahertz quantum cascade lasers
The effects of many-body coulomb interaction and non-parabolicity on optical gain of terahertz quantum cascade lasers are investigated based on the density-matrix model. The results show that many-body interaction and non-parabolicity effect all red-shift the gain spectrum and reduces the peak value...
