Терагерцовые излучатели с активной областью на основе сверхмногопериодных решеток AlGaAs/GaAs

Abstract

In this article, several designs of the active region of the THz radiation source are considered, taking into account grown super-multiperiod AlGaAs/GaAs superlattices. For the proposed designs, the principal device characteristics are computed: energy band diagram, gain spectrum, and transport characteristics. Based on the calculation results, the authors proposed an optimal design of the active region of a tunable THz radiation source.
