Abstract
An electromagnetic energy transmitting device includes a processing unit, a light-detecting sensor coupled to the processing unit, and a high-flux electromagnetic energy transmitter. An electromagnetic energy receiver arranged to convert received light into electricity. A first fiber-based conduit couples the high-flux electromagnetic energy transmitter to the electromagnetic energy receiver. The first fiber-based conduit is arranged to pass high-flux light from the high-flux electromagnetic energy transmitter to the electromagnetic energy receiver. A second fiber-based conduit couples the electromagnetic energy receiver to the light-detecting sensor. The second fiber-based conduit is arranged to pass at least some light from the electromagnetic energy receiver to the light-detecting sensor, wherein the processing unit is arranged to control an output of the high-flux light from the high-flux source based on a control signal from the light-detecting sensor.
