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, radio-over-fiber (RoF) communication system is now an efficient and cost-effective way to distribute synchronized photonic MMW signals from the central office to multiple base stations. In this talk, 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 will be described. 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 in-building and in-home applications, operating from 75 to 110 GHz.
About the speaker
Ci-Ling Pan is Tsing Hua Chair Professor, Chairperson of the Department of Physics and Institute of Astronomy, National Tsing Hua University (NTHU), Hsinchu, Taiwan. He also held joint appointment at the Institute of Photonics Technologies and served as Director of the Photonics Research Center of NTHU. Prof. Pan taught at National Chiao Tung University, Taiwan, 1981-2009. He also held visiting professorship at Osaka University and Chinese University of Hong Kong in 2004 and 2008, respectively. In the past decade, the main foci of Prof. Pan's research activities have been Ultrafast and THz Photonics. Recent research highlights include developments of functional liquid crystal THz photonic devices, femtosoeocnd-laser recrystallization and activation of silicon as well as novel THz generators and detectors. The latter were used in diverse applications such as diagnostics of technologically important materials for photovoltaics, assessing burn trauma and optical-network-compatible W-band (100 GHz or 0.1 THz) wireless communication Link at a data rate beyond 20 Gbit/s. Prof. Pan is a Fellow of APS, IEEE, OSA, and SPIE.
