A Terahertz Modulator

We’re all used to the changes in the properties of radio frequency systems as the frequency increases and the wavelength becomes shorter. The difference between the way an FM radio and a WiFi adapter behave with respect to their environments, for instance. But these are relatively low frequencies in the scheme of electromagnetic radiation, as you will be aware with ever shorter wavelengths those properties change further until eventually we are not dealing with something we’d describe as radio, but infrared light. Terahertz waves are the electromagnetic radiation that lies in that area between radio frequencies and infra-red light. You might expect that since science has delivered so many breakthroughs in both radio and IR, we’d have mastered them, but so far very few devices capable of working at these wavelengths have been developed. A Nature paper from a group at Tufts ...
