Terahertz radiation of microcavity dipolaritons [PDF]
Optics Letters, 2019 We propose the use of dipolaritons-quantum well excitons with a large dipole moment, coupled to a planar microcavity-for generating terahertz (THz) radiation. This is achieved by exciting the system with two THz detuned lasers that leads to dipole moment oscillations of the exciton polariton at the detuning frequency, thus generating a THz emission. We

Flat liquid jet as a highly efficient source of terahertz radiation. [PDF]
Optics Express, 2019 Polar liquids are strong absorbers of electromagnetic waves in the terahertz range, therefore, historically such liquids have not been considered as good candidates for terahertz sources.

Design of a tunable, room temperature, continuous-wave terahertz source and detector using silicon waveguides [PDF]
, 2008 We describe the design of a silicon-based source for radiation in the 0.5-14 THz regime. This new class of devices will permit continuously tunable, milliwatt scale, cw, room temperature operation, a substantial advance over currently available ...

Electrical and radiation characteristics of semilarge photoconductive terahertz emitters [PDF]
, 2004 We present experimental characterization of semilarge photoconductive emitters, including their electrical/photoconductive parameters and terahertz spectra. A range of emitters were studied and fabricated on both LT-GaAs and SI-GaAs, having a variety
