Title:
HEATING-TYPE LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2018/182013
Kind Code:
A1
Abstract:
A heating-type light source (5) provided with a radiation part (7) that is heated in accordance with heat transmitted from a heat source (10) and that radiates a light beam amplified at a specific wavelength higher than the visible light region on the basis of surface plasmon resonance. The radiation part (7) includes: a metal structure layer (16) that includes a two-dimensional arrangement of metal island parts or metal particles, and/or a metal layer in which openings are arranged periodically in a two-dimensional configuration; a dielectric layer (14) disposed further toward the heat-source (10) than the metal structure layer (16); and a base metal layer (12) provided so that the dielectric layer (14) is disposed between the base metal layer (12) and the metal structure layer (16). At least some of the radiation from the heat-source (10) side is blocked by the base metal layer (12).
