Abstract

The changes in the impedance of an antenna-coupled photo-detector under optical illumination are used to encode data on a backscattered wireless signal similarly to the standard techniques used for radio frequency identification and tagging. The effect is strong enough to allow retrieval of the information without requiring a dc supply at the optical to wireless interface. © 2001-2012 IEEE.
