Multi-mJ terahertz generation in periodically poled Lithium-Niobate by pulse recycling with dispersion compensation [PDF]

EPJ Web of Conferences, 2019
We propose a design for high efficiency narrow-band terahertz generation using multiple stages with dispersion compensation. Terahertz efficiencies of a few percent are predicted.

Generation of spontaneous parametric down-converted photons in the sub-terahertz frequency range at 660 nm

, 2022
S.518-519There are two crucial steps towards terahertz quantum sensing. First, there is the challenge to deliver a source of entangled photons in the terahertz range.

Experimental Comparison of UTC- and PIN-Photodiodes for Continuous-Wave Terahertz Generation

, 2022
S.343-354We carried out an experimental comparison study of the two most established optoelectronic emitters for continuous-wave (cw) terahertz generation: a uni-traveling-carrier photodiode (UTC-PD) and a pin-photodiode (PIN-PD).
