Terahertz radiation—the band of the electromagnetic spectrum between microwaves and visible light—has promising applications in medical and industrial imaging and chemical detection, among other uses. But many of those applications depend on small, power-efficient sources of terahertz rays, and the standard method for producing them involves a bulky, power-hungry, tabletop device. For over 20 years, Prof. Qing Hu at MIT, and his group have been working on sources of terahertz radiation that can be etched onto microchips...
