Room-temperature THz photon detection via nonlinear upconversion with 2% full-system efficiency
Aswin Vishnuradhan, Wei Cui, Hesam Heydarian +5
Sensitive detection of terahertz (THz) radiation is fundamental to progress in spectroscopy, advanced wireless communication, and the realization of emerging quantum technologies.…
Characterization of Terahertz Spectral Bands for Next Generation of Wireless Communications
Eeswar Kumar Yalavarthi, Wei Cui, Aswin Vishnuradhan +4
The ever-increasing demand for high-speed data transmission continues to motivate research and development efforts towards the sixth generation (6G) of wireless communication techn…
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…
