Abstract :
Terahertz (THz) waveguide emitters are presented as an alternative to conventional THz generation using, e.g. a photoconductive switch. Especially their ability to launch THz waves in subwavelength size waveguides is studied and the emitters are demonstrated to be useful THz sources to explore nanofabricated devices such as microcavity quantum cascade lasers.
