Terahertz quantum cascade lasers

The 16th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2003. LEOS 2003., 2004
We report our successful development of THz quantum cascade lasers with two unique features. The intersubband gain medium is based on resonant optical phonon scattering to depopulate the lower lasing level, and the THz mode confinement is achieved using a metal-semiconductor-metal waveguide.

Widely tunable compact terahertz gas lasers

Science, 2019
Filling the terahertz gapCompared with other wavelengths, coherent sources of electromagnetic radiation in the terahertz regime are relatively scarce. Despite a number of applications in security imaging, spectroscopy, and chemical analysis, it has been experimentally challenging to produce such light.

Bosonic Cascade Terahertz Lasers

CLEO: 2013, 2013
Emission of terahertz radiation may be stimulated in a bosonic system, where the final state occupation is significant. Polariton lasers represent such a system, which occupation numbers of 10000 or more for a polariton condensate are achievable at room temperature.

Terahertz quantum cascade lasers

(CLEO). Conference on Lasers and Electro-Optics, 2005., 2005
We provide an overview of terahertz quantum cascade lasers based on resonant-phonon depopulation and metal-metal waveguides, including two-phonon resonant-phonon depopulation schemes, long wavelength operation, and real time terahertz imaging.
