The terahertz (THz) quantum cascade laser (QCL), first demonstrated in 2002, is among the
most promising radiation sources in the THz region owing to its high output power and broad …

Quasi-two-dimensional lead halide perovskites, MA n–1Pb n X3 n+ 1, are quantum confined
materials with an ever-developing range of optoelectronic device applications. Like other …

We study an asymmetric double InGaAs quantum well using optical two-dimensional
coherent spectroscopy. The collection of zero-quantum, one-quantum, and two-quantum two …

We experimentally investigated the effect of oscillator strength (radiative transition
diagonality) on the performance of resonant phonon-based terahertz quantum cascade …

We designed and demonstrated a terahertz quantum cascade laser based on indirect pump
injection to the upper lasing state and phonon scattering extraction from the lower lasing …

In this paper, we used the 8-band k· p model with valence force field considerations to
investigate the effect of size and shape on electronic and optical properties of cadmium …

A terahertz quantum cascade laser is presented in which selectively placed pure AlAs
barriers are used to reduce parasitic leakage currents to the conduction band continuum …

Dephasing in terahertz quantum cascade structures is studied within a density matrix
formalism. We self-consistently calculate the pure dephasing time from the intrasubband …

Microscopic density matrix analysis on the linewidth enhancement factor (LEF) of both mid-
infrared (mid-IR) and Terahertz (THz) quantum cascade lasers (QCLs) is reported, taking …

We analyze the main physical processes in quantum cascade lasers with a spatial
separation between the region of photon radiation and longitudinal optical (LO) phonon …
