Experimental Demonstration of a Full-Duplex Indoor Optical Wireless Communication System

In this letter, a high-speed full-duplex indoor optical wireless communication system for both down-link and up-link is experimentally demonstrated. The feasibility of simultaneous error-free (bit-error-rate or BER <; 10
^-9
) operation of both a 10-Gbps down-link and a 500-Mbps up-link with a beam footprint of ~1 m has been demonstrated. Negligible power penalty due to the crosstalk is observed. When this full-duplex system is incorporated with our recently proposed novel optical wireless localization system, error-free operation can be provided over the entire room.
