Sub-zeptojoule detection of terahertz pulses by parametric frequency upconversion
Défi Junior Jubgang Fandio, Aswin Vishnuradhan, Eeswar Kumar Yalavarthi +4
We combine parametric frequency upconversion with single-photon counting technology to achieve detection sensitivity down to the terahertz (THz) single-photon level. Our relatively…

High-field THz source centered at 2.6 THz
Wei Cui, Eeswar Kumar Yalavarthi, Aswin Vishnu Radhan +3
We demonstrate a table-top high-field terahertz (THz) source based on optical rectification of a collimated near-infrared pulse in gallium phosphide (GaP) to produce peak fields ex…
