ABSTRACT
The temperature performance of type-II semiconductor lasers has been analyzed by comparing the temperature-concentration dependence for a charge-carrier subsystem at the threshold with steady-state temperature-concentration relationship implied by the carrier heating process. The low material gain characteristic of type-II heterostructures and the high resistance of the thermal link to the heat sink are primarily responsible for limiting the continuous-wave laser operation to low temperatures. We show also that the number of cascades for type-II interband cascade lasers can be optimized with respect to the highest achievable operating temperature.
