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…

Performance analysis of table-top single-pulse terahertz detection up to 1.1 MHz
Nicolas Couture, Markus Lippl, Wei Cui +3
Slow data acquisition in terahertz time-domain spectroscopy (THz-TDS) has hindered the technique's ability to resolve "fast" dynamics occurring on the microsecond timescale. This t…
