Terahertz (THz) radiation is currently attracting considerable interest for imaging and sensing applications, because it has the potential to supersede x-rays that are more damaging. THz radiation, however, has very low energy, which makes it challenging to detect.

High Speed Integrated Circuits Group at UC San Diego have succeeded in developing the technology and very high-gain ( 30-50dB) ultra-wideband (1-110GHz) and high-sensitivity THz front-ends on a silicon chip.

Physicists and industrialists are turning to terahertz radiation to provide cheaper, safer and more versatile ways of producing detailed images.
