Patent ID: 11870204
Assignee: KYOCERA CORPORATION
Field: Optics (Instruments)
Classification: CPC H  G  Y | IPC G  H

Claim 0:
1. An optical power supply system comprising:
a first data communication device including
a power sourcing equipment (PSE) device, the PSE device including
a first semiconductor laser configured to oscillate with electric power, and output feed light, and

a first transmitter including
a second semiconductor laser configured to output first laser light, and
a first modulator configured to modulate the first laser light and output first signal light; and

a second data communication device including
a powered device comprising a photoelectric conversion element configured to convert the feed light into the electric power, the photoelectric conversion element including a semiconductor region exhibiting a light-electricity conversion effect,
a receiver configured to demodulate the first signal light to an electric signal, and output the electric signal,
a data processing unit configured to receive the electric signal and output data based on the electric signal, and
a second transmitter including
a third semiconductor laser configured to output second laser light, and
a second modulator configured to modulate the second laser light to a second signal light based on the data, and output the second signal light to the first data communication device,

wherein the first data communication device and the second data communication device perform optical communication with each other, and
the electric power obtained by the conversion of the feed light by the photoelectric conversion element is driving power for the second transmitter and the receiver.
