Abstract

Optical Wireless Communication (OWC) systems are limited in bandwidth by their electro-optical components. We study the receiving photo diode, its surface area and the associated capacitance. A large–area detector improves the signal–to–noise ratio, but a small size allows a high bandwidth. An optimum detector size exists. It depends on photodiode properties, the trans-impedance amplifier noise performance and the received signal strength. Results are relevant to the design of indoor LiFi systems with wide coverage as well as for tracking acquisition in long–range free space optical applications.
