Biography:
Ci-Ling Pan is Vice President for Research, Tsing Hua Chair Professor, Department of Physics, National Tsing Hua University (NTHU), Hsinchu. He also holds joint appointment at the Institute of Photonics Technologies of NTHU. Prof. Pan taught at National Chiao Tung University, 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 pioneering the field of liquid crystal THz photonics, femtosoeocnd-laser recrystallization and activation of silicon for TFT 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 received numerous awards for his accomplishments. He is a Fellow of APS, IEEE, OSA and SPIE, an Academian of the Asia-Pacific Academy of Materials (APAM). Currently, he also serves as a Traveling Lecturer of OSA and member of Commission C17 (Quantum Electronics) of IUPAP.


报告摘要:
二十一世纪的信息社会对高于1 Gbit/s的无限信息传输速率需求孔急,由于无线电波频道在较低频段已太过拥挤,且无法负荷 10 Git/s以上的以太网络,利用W-频段(约100 GHz)或更高频的毫米波作为载波以实现高速数据传输的技术极受瞩目。然而,无论是在自由空间或是同轴电缆中,毫米波讯号在传输过程中都有很大的损耗。为突破此困境,我们发展将毫米波讯号载在光波上,透过光纤传输的新技术。结合光电式毫米波源与积体光电毫米波发射技术,成功展示超高速的光纤无线通讯技术,经光纤传输25km后,发射W-频段(0.1THz)无线讯号,传输率可超过每秒20Gbit/s(200亿位),相当于在20秒内下载10张高画值DVD(4.7Gbytes/disk)的全部信息)。我们也证实可以利用100GHz毫米波上传信息,这对远距医疗传输相当重要。此外,偏远地区或山区也能利用这个方法,分享网络的丰富资源。毫米波无线光纤通讯之关键组件及技术有二:其一是用光电技术产生获得要上载到光纤的次兆赫波讯号,且能将之不失真的经由光纤传到数十公里外。另一个关键技术是光电式的兆赫波发射器(photonic THz transmitter),将载在光纤上的~100GHz讯号与数据以无线电波的形式传播出去,我们开发的发射器拥有高频宽、高功率和低损失的特质,也因此不需要使用昂贵而复杂的放大器,这是强化讯号与降低成本的关键。


Abstract:
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 in-building and in-home applications, operating from 75 to 110 GHz.
