Quantum cascade lasers are, by far, the most compact, powerful, and spectrally pure sources of radiation at terahertz frequencies, and, as such, they are of crucial importance for applications in metrology, spectroscopy, imaging, and astronomy, among

Quantum cascade lasers are compact sources, but simultaneously achieving cw operation, low divergence and single-mode emission has proven difficult. Here, Biasco et al. use a combination of distributed feedback and outcoupling via hole arrays, improv

Millimeter wave (mmWave) generation using photonic techniques has so far been limited to the use of near-infrared lasers that are down-converted to the mmWave region. However, such methodologies do not currently benefit from a monolithic architecture

Terahertz Emitters, Receivers, and Applications X.
The quantum cascade laser (QCL) has been central to the development of terahertz (THz) science and technology in the last decade, thanks to its electronic and optical properties, which can be accurately tailored with quantum and photonic engineering.

We report on the study of phonon polaritons modes in thin crystalline flakes of Bi 2 Se 3 and Bi 2 (Te 1-x Se x )3 as a function of the flake thickness, by means of two near-field THz techniques: phase resolved self-detection and THz time domain spec
