Field: Optics (Instruments)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A wireless optical charging system, comprising:
a transmitter which transmits a wireless optical charging light source (optical source) beam as light with an energy increased by resonance; and
a receiving unit which receives light transmitted from the transmitter and converts an energy for some light among the received light into an electric energy to charge devices,
wherein the energy of light increases due to the resonance that occurs between the transmitter and the receiving unit due to the light reflected from the receiving unit to the transmitter,
wherein the transmitter includes:
a light source unit;
a diffraction grating, a prism, or an arrayed waveguide grating which divides light received from the light source unit into wavelengths in a predetermined range to output the light onto a space; and
a collimator which is disposed between the light source unit and any one of the diffraction grating, the prism, and the arrayed waveguide grating to convert light output from the light source unit into a collimated ray.
