A focal-plane array (FPA) for room-temperature detection of 0.65-THz radiation has been
fully integrated in a low-cost 0.25 mum CMOS process technology. The circuit architecture is …

We present the first superconducting hot electron bolometer (HEB) waveguide mixer
operating at 4.7 THz. The 5.5-nm-thick, 300-nm-long, and 3600-nm-wide NbN HEB …

We report precision measurements of the effective input noise temperature of a cryogenic
(liquid-helium temperature) monolithic-microwave integrated-circuit amplifier at the amplifier …

Contrary to the common belief, silicon devices may very well operate beyond their cut-off
frequency. The push towards terahertz frequencies, though, presents both challenges and …

Microwaves can penetrate many obstructions that are opaque at visible wavelengths,
however microwave imaging is challenging due to resolution limits associated with relatively …

We have developed 585-GHz quasi-optical mixers and focal-plane arrays (FPAs) comprised
of planar annular slot antennas (ASAs) with integrated niobium hot-electron bolometers for …

GUSTO will be a NASA balloon borne terahertz observatory to be launched from Antarctica
in late 2021 for a flight duration of 100-170 days. It aims at reviewing the life cycle of …

We present measurement results for a new type of integrated terahertz receiver, as an
extension to previous work by the authors. The receiver we developed integrates quasi …

We report on the development and characterization of a passive heterodyne hot electron
bolometer (HEB) imager operating at 850 GHz. HEB detectors provide unprecedented …

We report on heterodyne measurements at submillimeter wavelengths using a receiver with
a Superconductor-Insulator-Superconductor (SIS) mixer device and a Microwave Monolithic …
