Patent ID: 11901742
Assignee: INDUSTRY ACADEMY COOPERATION FOUNDATION OF SEJONG UNIVERSITY
Field: Optics (Instruments)
Classification: CPC H  G | IPC G  H

Claim 7:
8. The wireless optical charging system of claim 3, wherein the light source unit includes:
a single mode optical fiber having one light propagation mode;
an optical fiber laser which is formed on a path of the single mode optical fiber so that an output is adjustable to output light in a broadband;
a laser pump which adds light of an external source to the single mode optical fiber;
a WDM coupler which couples a wavelength to light added from the laser pump and light of the single mode optical fiber;
an isolator which transmits light only in one direction;
a polarization control unit which is formed at an input end and an output end of the optical fiber laser to maintain polarization of light; and
a coupler which receives a power from the collimator and outputs a broadband light source from the optical fiber laser to the diffraction grating.
