A novel slot waveguide with tunable, two-dimensional electron gas could form the basis of a room temperature THz modulator, according to Massachusetts-based Tufts University. Through lack of THz facilities, the researchers have created a lower frequency prototype, than can amplitude modulate a 250GHz carrier to 96% intensity with a 14GHz signal. “This is a very ...
