| Popis: | We propose a full-duplex dynamic indoor optical-wireless communication system using a crossed pair of diffraction gratings and photonic-integrated circuits with multicasting capability of 10-Gb/s on-off-keying and >40-Gb/s discrete-multitone data per user, backed up by a 60-GHz radio fallback system, with shared capacity of ∼40 Gb/s to realize reconfigurable and reliable high-capacity links to wireless users equipped with localization and tracking functionalities. The use of semiconductor optical amplifiers integrated with reflective electroabsorption modulators allows us to provide cost-efficient reflective transmitters at the user terminals in the upstream using centralized light sources and wavelength reuse technique. The 60-GHz radio fallback system allows us to cope with line-of-sight blocking in the optical-wireless links, thereby significantly enhancing the reliability of the wireless communication system. |
