Carbon Nanotube Terahertz Detector

Nano Letters, 2014
Terahertz (THz) technologies are promising for diverse areas such as medicine, bioengineering, astronomy, environmental monitoring, and communications. However, despite decades of worldwide efforts, the THz region of the electromagnetic spectrum still continues to be elusive for solid state technology. Here, we report on the development of a powerless,

Metamaterial based terahertz detector

2011 International Conference on Infrared, Millimeter, and Terahertz Waves, 2011
We present a metamaterial based terahertz (THz) detector. The detector design, which combines metamaterials and MEMs, is frequency selective, and we have fabricated and tested detectors at 95 GHz and 693 GHz with noise equivalent powers of 1.13 × 10−8 W/√Hz and 2.96 × 10−8 W/√Hz and responsivities of 16,500 V/W and 6,800 V/W, respectively. These values

Inexpensive detector for terahertz imaging

Applied Optics, 2007
Glow discharge plasma, derived from direct-current gas breakdown, is investigated in order to realize an inexpensive terahertz (THz) room-temperature detector. Preliminary results for THz radiation show that glow discharge indicator lamps as room-temperature detectors yield good responsivity and noise-equivalent power.

Terahertz sources and detectors

SPIE Proceedings, 2005
Through the support of the US Army Research Office we are developing terahertz sources and detectors suitable for use in the spectroscopy of chemical and biological materials as well as for use in imaging systems to detect concealed weapons. Our technology relies on nonlinear diodes to translate the functionality achieved at microwave frequencies to ...
