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

Claim 9:
10. The wireless optical charging system of claim 1, wherein the transmitter further includes:
a light splitter which is disposed at an output end of the light source unit to split light incident from the light source unit into two and transmit the light to the direction control unit and the diffraction grating, and
the light source unit includes:
a plurality of direction switching mirrors which switches a moving direction of light to form a moving path of light;
a semiconductor optical amplifier which is formed on the moving path to provide a broadband gain spectrum having a signal gain for the light;
an isolator which transmits light only in one direction of the moving path; and
a collimator which is disposed between the semiconductor optical amplifier and the isolator to convert light output from the semiconductor optical amplifier into a collimated ray.
