Although terahertz (THz) radiation was first observed about hundred years ago, the
corresponding portion of the electromagnetic spectrum has been for long time considered a …

In the last decade quantum cascade lasers (QCLs) have become the most widely used
source of mid-infrared radiation, finding large scale applications because of their wide …

We report the demonstration of a terahertz quantum-cascade laser that operates up to 164 K
in pulsed mode and 117 K in continuous-wave mode at approximately 3.0 THz. The active …

Intense Terahertz Excitation of Semiconductors presents the first comprehensive treatment
of high-power terahertz applications to semiconductors and low-dimensional semiconductor …

The National Institute of Information and Communications Technology (NICT, Japan) started
the Terahertz Project in April 2006. Its fundamental purpose in the next five years is to …

The design and projected performance of quantum-well infrared photodetectors QWIP for
the terahertz 1–10 THz or the very-far-infrared region are presented together with our initial …

Terahertz (THz) quantum cascade laser (QCL) is an electrically pumped unipolar photonic
device in which light emission takes place due to electronic transitions between subbands …

We report the operation of a quantum cascade laser emitting at a 103 m wavelength 2.9
THz. The active region is based on a bound-to-continuum design allowing a low parasitic …

A density matrix approach is used in combination with a tight-binding model to describe
electron transport in terahertz quantum cascade lasers and is incorporated into a Monte …

We report cw operation of a quantum-cascade laser at 3.2 THz (λ≈ 94 μm) up to a heat-sink
temperature of 93 K. Resonant longitudinal-optical phonon scattering is used to depopulate …
