Superconducting detectors will play an increasingly significant role in astrophysics,
especially at millimeter through far-IR wavelengths, where the scientific opportunities …

The concept of a fully superconducting integrated receiver is developed and experimentally
tested. This single-chip sub-mm wave receiver includes a planar antenna integrated with a …

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 …

For four decades semiconductor electronics has followed Moore's law: with each generation
of integration the circuit features became smaller, more complex and faster. This …

We have developed a low-noise 850 GHz superconductor–insulator–superconductor
quasiparticle mixer with NbTiN thin-film microstrip tuning circuits and hybrid Nb/AlN/NbTiN …

The design and optimization of very broadband integrated lens antennas (ILAs) constitutes
one of the future trends in lens antenna field. To this end we investigate numerically the …

We have fabricated and tested submillimeter-wave superconductor–insulator–
superconductor (SIS) mixers using very high-current-density Nb/AlN/Nb tunnel junctions (J …

The intermediate frequency (IF) characteristics, the frequency dependent IF impedance, and
the mixer conversion gain of a small area Hot Electron Bolometer (HEB) have been …

Recent results at 1 THz using normal-metal tuning circuits have shown that SIS mixers can
work well up to twice the gap frequency of the junction material (niobium). However, the …

We describe a new dual-polarized slot antenna to be used with quad-optical devices such
as superconductor-insulator-superconductor (SIS) mixers at millimeter and submillimeter …
