Paper Abstract

This paper reports on numerical analysis of longitudinal mode discrimination in coupled-cavity AlInAs/InGaAs/InP quantum cascade lasers. Using a three dimensional, self-consistent model of physical phenomena in edge emitting laser we performed exhaustive analysis of geometrical parameters of CC QCL on spectral characteristics. We discuss the enhancement of the single mode operation in multi-section designs concerning variable dimensions of sections and air gaps between sections and provide designing guidelines assuring single-mode operation. We also show impact of independent current tuning of laser sections inducing Stark effect and heating as additional elements enhancing single mode operation.
