Document Type and Number:
WIPO Patent Application WO/2023/223857
Kind Code:
A1
Abstract:
Provided is a power receiving device, a power feeding device, an optical power feeding system, a power receiving method, a power feeding method, and an optical power feeding method, by which power and information can be simultaneously transmitted through feeding light. Power is transmitted by delivering feeding light in which information is inserted by wavelength modulation; meanwhile, power is received such that the feeding light is received by a light receiving unit having different sensitivity according to a wavelength and the feeding light is converted into power, and information is extracted on the basis of the amount of power that changes according to a wavelength change of the feeding light.
