Title INFRARED LIGHT ELEMENT meetings
Abstract Provided is a compact infrared light element that performs light emission or detection in the infrared to Thz region and operates at room temperature. An infrared light element according to one aspect of the present invention is obtained by forming striped, lattice-shaped, or ring-shaped conductors on a semiconductor or insulator substrate, the intervals therebetween being no more than 1/2 the wavelength of infrared light that resonates with the longitudinal optical (LO) phonon energy, and the infrared light element emits or detects infrared light that resonates with said mode. An infrared light element according to another aspect of the present invention is obtained by forming striped, lattice-shaped, or ring-shaped conductors on a semiconductor or insulator substrate, the intervals therebetween being no more than 1/2 the wavelength of infrared light that resonates with the LO phonon-plasmon coupled (LOPC) mode energy, and the infrared light element emits or detects infrared light that resonates with said mode.
