New imaging opportunities for medical and security applications may launch terahertz technology into the public domain. Semiconductor technology is key to many of these developments, says Dr Mike Cooke.
A new laser design helps create usable terahertz radiation, which penetrates common materials but doesn’t harm tissue.
“T-rays” have been touted as the next breakthrough in sensing and imaging, but the need for bulky equipment has been an obstacle to reaching the field’s potential. Enter Brian Schulkin, winner of the first-ever $30,000 Lemelson-Rensselaer Student Prize. Schulkin has invented an ultralight, handheld terahertz spectrometer  an advance that could help catapult T-ray technology from the lab bench to the marketplace.
The Department of Physics and Astronomy at Colgate University invites applications for a one-year postdoctoral teaching/research fellowship in physics to begin in the fall of 2007.
European researchers are developing high-frequency transistors based on a variety of radical technologies to power security-camera systems, probe distant galaxies and boost computer performance.
Cryogenic Detectors and Detector Arrays for: Terahertz, Infrared, Visible, X-ray and gamma ray detection and imaging; alpha particles; and mass spectrometry.
The group designs and manufactures Infrared/THz Instrumentation with applications in cosmology, astronomy, atmospheric remote sensing, plasma fusion diagnostics, materials measurement and a range of spectroscopic techniques.
Interferometric imaging provides both spatial and spectral information about screened objects with a limited number of expensive detectors.
The department of Electrical Engineering at UCLA has a Postdoctoral Scholar position available in the Terahertz Devices and Intersubband Nanostructures Laboratory for research on low-dimensional semiconductor nanostructures for optoelectronic and nanophotonic applications.
The candidate should have experience with designing devices and systems for operation in the 100 GHz 3 THz frequency range, expertise in measurements at these frequencies, and the ability to design and fabricate devices and/or electronic components for submillimeter applications.
