WHOF 88:Recent advances in millimeter-wave photonic wireless links for very high data rate communication

To meet the rapidly growing demand of gigabits wireless access applications,sub-THz or millimeter wave(MMW) carriers in W-band(75-110 GHz) or above are essential for obtaining the necessary broad transmission bandwidth.Thanks to the almost unlimited bandwidth and very low propagation loss in optical fiber,an efficient and cost-effective way to distribute synchronized photonic MMW signals from the central office to multiple base stations is a radio-over-fiber(RoF) communication system.In this paper,we will review our recent work on photonic wireless communication link at 100 GHz or 0.1 THz.Key technologies are photonic MMW sources and photonic MMW transmitters.Wireless data transmission at a data rate beyond 20-Gb/s via bias modulation of such novel device has been successfully achieved for both downlink and uplink.We have also demonstrated an optical ultra-wide band impulse-radio fiber-to-the-antenna(UWB-IR FTTA) system for inbuilding and in-home applications,operating from 75 to 110 GHz.
