High-Capacity Symmetric Dynamic Indoor Optical Wireless Communication Equipped With User Localization

We report on a novel all-optical system for ultra-high-capacity indoor wireless communication with centralized light sources. Using optical cross-connect and reflective modulator photonic chips, bidirectional dynamic indoor wireless networks equipped with localization and tracking functionalities are realized. This novel system allows us to harvest the ultimate bandwidth of optical communication in the wireless domain in a more cost-/energy-efficient manner. Bidirectional transmission capacities in excess of 40 Gb/s per user are demonstrated experimentally.
