Terahertz chip technology could replace costly equipment

22 Feb, 2017 09:00 am

A group of Princeton University researchers have developed a terahertz wave source and detection device the size of a single fingertip.

The microchip-sized system replaces much larger tabletop setups with lasers and mirrors used to send the terahertz waves.

The researchers wrote in two articles recently published in the IEEE Journal of Solid State Circuits that the development could serve as a cheaper and more efficient alternative to imaging systems that use electromagnetic waves to penetrate matter, such as x-ray machines.

"The system is realized in the same silicon chip technology that powers all modern electronic devices from smartphones to tablets, and therefore costs only a few dollars to make on a large scale," said lead researcher Kaushik Sengupta, a Princeton assistant professor of electrical engineering.
