Abstract
A system for optical wireless power transmission to a power receiving apparatus generally situated in a mobile electronic device. The transmitter has an optical resonator with end reflectors and a gain medium positioned between them, such that an optical beam is generated. The frequency of the beam is selected such that it is absorbed by almost all transparent organic materials in general use. A beam steering unit on the transmitter can direct the beam in any of a plurality of directions, and the beam is absorbed on the receiver by means of an optical-to-electrical power converter, through a low reflection surface. The band gap of this power converter is selected to be smaller than that of the gain medium. The receiver has a voltage converter including an inductor, an energy storage device and a switch. A beam steerer controller ensures that the beam impinges on the receiver.
