We show that low-threshold Risken-Nummedal-Graham-Haken (RNGH) instabilities in
quantum cascade lasers (QCLs) occur due to a combined effect of the carrier coherence and …

We have theoretically explored the influence of the magnetic field on supporting the
multimode Risken-Nummendal-Graham-Haken (RNGH) self-pulsations seen in the optical …

We analyze multimode instabilities in Fabry-Pérot (FP) cavity MIR quantum cascade lasers

An efficient method for simulating quantum transport in quantum cascade lasers is
presented. The calculations are performed within a simple approximation inspired by …

Two methods for calculating transport parameters in semiconductor superlattices by
applying Green's functions are compared in the paper. For one of the methods, the Wannier …

In this work, two-section, coupled cavity, mid-IR quantum cascade lasers (QCLs) were
characterized in terms of their tuning range and emission stability under operation towards …
