Found in many terahertz (THz) and submillimeter-wave systems, GaAs Schottky diodes
continue to be one of the most useful THz devices. As a low-parasitic device that operates …

Significance: An increasing interest in the area of biological effects at exposure of tissues
and cells to the terahertz (THz) radiation is driven by a rapid progress in THz biophotonics …

Even though the terahertz spectrum is well suited for chemical identification, material
characterization, biological sensing and medical imaging, practical development of these …

Six years after their birth, terahertz quantum-cascade lasers can now deliver milliwatts or
more of continuous-wave coherent radiation throughout the terahertz range—the spectral …

This review is focused on the latest developments in continuous-wave (CW) photomixing for
Terahertz (THz) generation. The first part of the paper explains the limiting factors for …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

New and emerging terahertz technology applications make this a very exciting time for the
scientists, engineers, and technologists in the field. New sensors and detectors have been …

This article presents some aspects of the technology of terahertz heterodyne receiver front-
ends dedicated to astrophysics, planetary and atmospheric sciences. It focuses on …

In the last couple of decades, solid-state device technologies, particularly electronic
semiconductor devices, have been greatly advanced and investigated for possible adoption …

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 …
