72Photonic Antennas - Residential and Theoretical Applications
Photonic antennas use optical wavelengths and photonic materials or components while carrying or processing signals. Such antennas can receive microwave signals such as TV signals and relay them to fiber-optic cable subscribers; they also receive cell phone signals and transmit the information to Voice over Internet Protocol users. Photonic antennas already exist in fiber-optic cable systems in private homes and businesses.
