Abstract:
A wavelength conversion device includes: a wavelength conversion element having a phosphor plate that converts the wavelength of incident light upon a light incident surface to generate wavelength-converted light, and emits the wavelength-converted light from a light emission surface; an antenna array constituted of a plurality of optical antennas that are periodically arranged on the light emission surface of the phosphor plate; and a recessed structure including at least one recessed portion provided in the light emission surface of the phosphor plate.
