Quantum cascade lasers are unipolar semiconductor lasers covering a wide range of the
infrared and terahertz spectrum. Lasing action is achieved by using optical intersubband …

Even though already in the seventies, right after the invention of the quantum cascade laser
(QCL) concept, it was argued that this device could be operated in the THz (far-infrared) …

We present a terahertz quantum cascade laser operating on a thermoelectric cooler up to a
record-high temperature of 210.5 K. The active region design is based on only two quantum …

Dissipative Kerr solitons are self-organized optical waves arising from the interplay between
the Kerr effect and dispersion. They can form in nonlinear microresonators by deliberately …

Quantum cascade lasers (QCLs) are high-power sources of coherent radiation in the
midinfrared and terahertz (THz) bands. Laser feedback interferometry (LFI) is one of the …

This paper is concerned with the dynamic solutions for forced vibrations of Timoshenko
beams in a systematical manner. Damping effects on the vibrations of the beam are taken …

We present homogeneous quantum cascade lasers (QCLs) emitting around 3 THz which
display bandwidths up to 950 GHz with a single stable beatnote. Devices are spontaneously …

Detailed simulations for terahertz quantum cascade lasers based on two-well designs are
presented. We reproduce the maximal operation temperatures observed and attribute the …

A general theoretical approach to study the quantum kinetics in a system coupled to a bath
is proposed. Starting with the microscopic interaction, a Lindblad master equation is …

We present a two-quantum well THz intersubband laser operating up to 192 K. The structure
has been optimized using non-equilibrium Green's function model. The result of this …
