Microstructures Emit Coherent IR Radiation
Jun 1, 2002 — Thermal sources, such as a blackbody or the incandescent filament in a lightbulb, typically produce broadband, quasi-isotropic radiation. But a team at Centre National de la Recherche Scientifique in Châtenay-Malabry and Bagneux, France, and at Commissariat a l'Energie Atomique in Le Barp, France, has demonstrated that this need not be the case by developing a microstructured source that acts like an infrared antenna, generating coherent mid-infrared radiation in narrow emission...
