Optical Wireless Communication at a glance
Optical Wireless Communication (OWC) is a research field in which light is used to send information without guiding it as it occurs in an optical fiber. Despite this main difference, both schemes (fiber and OWC) are usually based on Intensity Modulation / Direct Detection (IM/DD). Under IM/DD, optical sources are current-driven and photodetectors convert optical power to a flow of electrons. These two opto-electrical conversion steps make OWC more sensitive to distance than Radio Frequency (RF) systems. The following equation illustrates this effect.
