The discovery of hot-electron phenomena in a thin superconducting film in the last century
was followed by numerous experimental studies of its appearance in different materials …

The high sensitivity detection of terahertz radiation is crucial for many chemical sensing,
biomedical imaging, security screening, nondestructive quality control, high-data-rate …

In modern astronomy and astrophysics, chemistry is becoming increasingly important.
Molecules are found everywhere in the universe owing to rapid progress of spectroscopic …

We present the upGREAT THz heterodyne arrays for far-infrared astronomy. The low-
frequency array (LFA) is designed to cover the 1.9-2.5 THz range using 2× 7-pixel …

Micromachined packaging is emerging as the best choice for development of terahertz
multipixel heterodyne array instruments and other advanced terahertz systems. Traditional …

We review the development of multi-pixel heterodyne receivers for astronomical research in
the submillimeter and terahertz spectral domains. We shortly address the historical …

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 …

It is difficult to package and interconnect components and devices at millimeter-waves (mm-
waves) due to excessive losses experiences at these frequencies using traditional …

In this paper, a 400-GHz silicon micromachined elliptic cavity waveguide filter with two
transmission zeros on both sides of the passband is presented. The filter is cascaded by two …

The HEterodyne Receiver for the Origins Space Telescope (HERO) is a proposed design for
a heterodyne focal plane array for a large space mission. The Origins Space Telescope …
