A graphene-based terahertz modulator

graphene_device-xuequan_chen.jpg A joint collaboration between the Chinese University of Hong Kong and the University of Warwick has developed an efficient and broadband modulator of THz radiation. By reflecting THz radiation from a conductive, gated graphene layer the team have shown that the amplitude of THz radiation pulses can be modulated by more than 99%. Further, phase modulation was acheived by working above Brewster's angle. The findings are described in a recent article in Nature Communications, and are described in an article in Physics World.

Welcome to our new PhD students - Hannah, Helen, Edward and Xavier

A very warm welcome to our 4 new PhD students, who have just started their THz adventures! Hannah and Xavier are working with Emma on THz imaging and biomedical applications, while Helen (supervised by Becky) and Edward (supervised by James) are studying the wonderful world of perovskite semiconductors. Best of luck.

Welcome to Dr Rebecca Milot

We would like to welcome Dr Rebecca Milot to the department, where she started as an Asst. Prof. in September. Dr Milot is an expert on terahertz spectroscopy of materials for solar energy applications. She is based in Physics 2.32 and is setting up a new lab in Physics, as well as making use of the existing Ultrafast & THz group labs. Welcome Becky!
