Limiting facors for high temperature operation of THz quantum cascade lasers
We theoretically investigate the temperature dependence of the carrier transport in GaAs-based THz quantum cascade lasers and identify the factors restricting high-temperature operation. In this context, we compare a single- to a double-resonant-phonon depopulation design.
