Quantum cascade lasers (QCLs) emit in the mid-infrared and terahertz range and are suitable for self-starting fundamental and harmonic mode-locking. The combination with low-noise quantum cascade detectors, which are required for the detection of nonlinear and nonclassical properties in QCL emission, can pave the way for next-generation high-performance applications and open up fascinating perspectives for quantum science. In this thesis, we present a multi-domain modeling approach for fully time-dependent and self-consistent simulations of such intersubband quantum cascade devices.
