Title:
POWER-FEEDING DEVICE, POWER-RECEIVING DEVICE, AND OPTICAL FIBER POWER-FEEDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/014845
Kind Code:
A1
Abstract:
Provided are a power-feeding device, a power-receiving device, and an optical fiber power-feeding system with which it is possible to transmit energy and information using power-feeding light and suppress the transmitted information from affecting the magnitude of transmitted energy. The power-feeding device comprises a laser oscillation unit for converting electric power to power-feeding light, and a modulation unit for phase-modulating the power-feeding light outputted from the laser oscillation unit on the basis of transmitted information, the power-feeding device sending the power-feeding light which is phase-modulated by the modulation unit to the power-receiving device via an optical fiber. The power-receiving device comprises a photoelectric conversion element for converting the received power-feeding light to electric power, and a demodulation unit for detecting the phase of the power-feeding light, the transmitted information being extracted from the demodulation result of the demodulation unit.
