Lasers diodes convert electrical power to a highly collimated beam of Optical power that may propagate over meters with insignificant losses. At the the other end of this optical link Photovoltaic diodes may be used to retrieve electrical power. This point-to-point wireless power transmission is safe if all the optical power is accounted for using an information feedback from the receiver. In addition, safety can also be guaranteed by monitoring the periphery of the optical beam. Optical fields…
