Hybrid Optical Wireless Power and Data Transmission System

Hybrid optical wireless power and data transmission which can be used to transmit power and real time data simultaneously has been developed. Two lasers with different wavelengths are used as the transmitter for power and data transmitter. To combine and separate the transmission axes of the laser beams for power and data transmission, dichroic mirrors are used at the transmitter and receiver, respectively. 150 mW optical power and 10 MHz 3-dB bandwidth data transmission has been successfully demonstrated.
