Employing an ensemble Monte Carlo transport simulation, we self-consistently analyze the
spectral gain for different terahertz quantum cascade laser structures, considering bound-to …

A theoretical study is presented to assess the performance of semiconductor superlattice
(SL) multipliers as a function of the currently available input power sources. The prime …

The possibility of using the self-induced transparency effect to achieve laser mode locking
has been discussed since the late 1960s but has never been observed. In prior work, we …

We present a method for self-consistently including the optical cavity field into Monte Carlo-
based carrier transport simulations. This approach allows for an analysis of the actual lasing …

This paper applies the Keldysh nonequilibrium Green's-function formalism to introduce the
concept of k-space filtering due to the strong localization of the intervalence transverse …

We overview the results of recent experimental and theoretical studies of nonlinear
dynamics of mid-infrared quantum cascade lasers (QCLs) associated with nonlinear …

We investigate the possibility of interconduction band gain without global inversion by
engineering the conduction band effective masses so that the upper lasing subband has an …

This paper describes microscopic calculations of photocurrent generation spectra due to
intersubband transitions in semiconductor heterostructures that can extract energy from …

In recent years, quantum cascade lasers have emerged as mature semiconductor sources of
light in the terahertz range, the frequency range spanning 1 to 10 THz. Though technological …

The temperature dependence of coherent carrier transport in quantum cascade lasers
(QCLs) is studied in this paper. It was found that coherent carrier transport in QCLs …
