Terahertz (THz) radiation—radiation in the wavelength range of 30 to 300 microns—is gaining attention due to its applications in security screening, medical and industrial imaging, agricultural inspection, astronomical research, and other areas. Traditional methods of generating terahertz radiation, however, usually involve large and expensive instruments, some of which also require cryogenic cooling. A compact terahertz source—similar to the laser diode found in a DVD player —operating at room temperature with high power has been a dream device in the terahertz community for decades.
