We propose a full-duplex dynamic indoor optical-wireless system using photonic integrated circuits with multicasting capability of 10 Gb/s on-off-keying data, backed up by a 60-GHz radio fallback system, with data capacity of >40 Gb/s to realize reconfigurable and reliable high-capacity links to wireless users equipped with localization and tracking functionalities.
We present an experimental demonstration of radio beamforming using an optical chip for application in K-band satellite communication. Via coherent combination of four RF channels, close to 12 dB beamforming gain is obtained. As a result, the transmission capacity is enhanced from 8-QAM, 5.81 Gbps to 32-QAM, 9.68 Gbps of multi-carrier data. For 4 channel beamforming, error-free performance (BER<1E-12)...
We demonstrate a novel all-optical system using optical cross-connect and reflective modulator photonic chips to realize bidirectional dynamic indoor wireless networks equipped with localization and tracking functionalities, with over 40 Gb/s data capacity per user.
We present a full-duplex dynamic indoor optical wireless system using 2D passive optical beam steering for downlink and 60-GHz communication for upstream transmission. We demonstrate 35-Gb/s NRZ-OOK downstream multicasting and 5-Gb/s NRZ-ASK upstream communication.
We present a future-proof network architecture for ultra-high capacity indoor wireless communication consisting of a hierarchical wavelength-based dynamic routing for downstream optical-wireless communication and 60-GHz radio-over-fiber (RoF) system with wavelength reuse in the upstream direction. Bidirectional transmission of 25 Gb/s is demonstrated using discrete-multi-tone modulation.
We present a bidirectional dynamic indoor fiber infrastructure using a photonic integrated cross-connect chip for optical wireless downstream and 60GHz radio-over-fiber upstream transmission. We demonstrate 10Gb/s on-off-keying downstream multicasting and 33Gb/s discrete-multi-tone upstream communication.
We report an indoor optical wireless communication system based on 2D optical beam steering at using arrayed waveguide gratings. A data rate of 10Gbps is demonstrated with NRZ-OOK modulation maintaining BER ≤ 10−9, while keeping the optical transmitted power below the eye safety limit.
