The state-of-the art of terahertz heterodyne receivers are reviewed. Emphasis is placed on
front-end components such as mixers and local oscillators. The back-end technology is …

The balloon-borne instrument TELIS (TErahertz and submillimetre LImb Sounder) is a three-
channel superconducting heterodyne spectrometer for atmospheric research use. It detects …

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 …

We have elaborated, fabricated, and tested a terahertz source based on the Josephson flux-
flow oscillator (FFO) integrated with a transmitting lens antenna. The oscillator was coupled …

We elaborate a theoretical description of large Josephson junctions which is based on
Werthamer's microscopic tunneling theory. The model naturally incorporates coupling of …

The flux-flow oscillator (FFO) based on a long Josephson junction has been implemented as
a broadband tunable terahertz (THz) source to open space. For this purpose, the …

The superconducting integrated receiver (SIR) comprising in one chip a superconductor-
insulator-superconductor (SIS) mixer and a phase-locked superconducting flux flow …

In some practical applications, devices based on superconducting electronics, due to their
unique set of parameters, are far superior to those based on conventional technologies …

TELIS (Terahertz and submm Limb Sounder) is a cooperative European project to develop a
three-channel heterodyne balloon-based spectrometer for measuring a variety of …

We have numerically investigated the dynamics of a long linear Josephson tunnel junction
with overlap geometry. Biased by a direct current (dc) and an applied dc magnetic field, the …
