Symmetric and antisymmetric band-edge modes exist in distributed feedback surface-
emitting semiconductor lasers, with the dominant difference being the radiation loss …

In this work, a design for a mid-infrared quantum cascade laser frequency comb source that

The fast modulation of lasers is a fundamental requirement for applications in optical
communications, high-resolution spectroscopy and metrology. In the terahertz-frequency …

We analyze the temperature performance of five terahertz (THz)-frequency quantum
cascade lasers based on a three-quantum-well resonant-phonon depopulation design as a …

In this work, we have studied the frequency response to a direct current modulation of a mid-
infrared quantum cascade laser that has been monolithically integrated within a microwave …

Various resonators for surface emission are reviewed that have recently been developed to
improve radiative‐and collection‐efficiencies of terahertz quantum cascade lasers (THz …

We compare the performance of 10 and 5 μm thick metal–metal waveguide terahertz
quantum-cascade laser ridges operating around 2.7 THz and based on a 4-well phonon …

HgCdTe is promising as a material to solve a problem of the development of semiconductor
sources with an operational frequency range of 6–10 THz due to the small optical phonon …

We demonstrate controlled optical critical coupling into highly confining metal-insulator-
metal grating-based resonators. We achieve the coupling—and hence the absorption—of …

We present the use of the cavity antenna model in predicting the radiative loss, far-field
polarization and far-field beam patterns of terahertz quantum-cascade (QC) lasers. Metal …
