Paper Abstract

An integrated photoconductive (PC) sensor is introduced as an optoelectronic element for visible light optical wireless communications (OWC) links. The sensor applies the standard PC switch, being a biased metal-semiconductor-metal gap, in a three-fold-symmetric corner-cube architecture with a summed output photocurrent at the vertex. Such a form facilitates bidirectional retroreflective communications to meet fundamental OWC requirements for broad directional and broad spectral capabilities. The ultimate OWC capability, for ultrafast optoelectronic switching times, is studied here for material response and transit time response, and it is shown that ultrafast (picosecond) optoelectronic switching times can be achieved and the general device design consideration is discussed for emerging visible light OWC systems.
