Officiating guests included Dr. the Honorable Lee Quo- wei ( 5th right ), chairman of the Wei Lun Foundation Ltd. and former chairman and life member of the Council, 物 理系劉仁保教授在 超高速光學通信研 究取得突破，可望將互聯網 速度提升上萬倍。研究成果 於新一期權威學術期刊《自 然》發表。 劉教授與加州大學聖芭芭拉 分校Mark Sherwin教授及 博士研究生Ben Zaks合作， 利用自由電子激光器照射半導體裝置，成功觀測到「光 梳」現象，為邁向高達每秒萬億位（Tb/s）計的高速光學通 信技術奠定了重要基礎。 CUHK, and Mrs. Lee ( 4th right ); Mr. Anthony Wu ( 3rd right ), chairman of the Hospital Authority; Dr. Vincent H.C. Cheng ( 4th left ), Chairman of the Council, CUHK; Prof. Joseph J.Y. Sung ( 3rd left ), Vice-Chancellor, CUHK; Mr. Edward Ho ( 2nd right ), chairman of the Hospital Governing Committee, PWH; Dr. Fung Hong ( 2nd left ), cluster chief executive, New Territories East Cluster; Prof. Fok Tai-fai ( 1st right ), dean of the Faculty of Medicine, CUHK; and Prof. Yu Cheuk-man ( 1st left ), chairman of the Department of Medicine and Therapeutics, Faculty of Medicine, CUHK and director of the Lee Quo Wei Cardiovascular Intervention Centre. Established in 2010, the centre comprises a multidisciplinary team and performs more than 2,500 invasive cardiovascular procedures every year. It serves a population of 1.3 million living in eastern New Territories, and acts as a referral centre for cardiovascular diseases in Hong Kong. At the opening ceremony, Professor Sung expressed his gratitude to the Lee family and the foundation for their generous and continual support. Their far-sighted vision not only allowed the centre to come into existence, but has also benefited patients by providing early diagnosis and proper treatment with cutting-edge technologies. 若有關技術應用於現實，傳輸一張四層的藍光碟或一個包 含百萬冊圖書的電子圖書庫只需一秒，較現時互聯網廣泛 採用的銅纜傳輸技術快上萬倍。中大將以物理系光學科學 中心為基地，與加州大學繼續合作該項研究。 P rof. Liu Renbao of the Department of Physics made a key breakthrough towards ultra high-speed optical communication that has potential to speed up the current Internet by 10,000 times. The research findings have been recently published in the prestigious journal Nature . Professor Liu and researchers Ben Zaks and Mark Sherwin at the University of California, Santa Barbara (UCSB) used free electron lasers to irradiate a semiconductor device, and observed THz frequency comb, i.e., modulation of light at one trillion times per second (Tb/s). The observed THz frequency comb is a key element in future optical communication at Tb/s rate. ‘If such high-speed communication comes into being, one could transfer a whole quadruple-layer blue-ray disc or an electronic library of one million books in only one second,’ Professor Liu commented. This new technology has the potential to transfer data 10,000 times faster than copper cables, on which the current Internet is widely based. Researchers at the Centre of Optical Sciences of CUHK will continue to work with its collaborators at UCSB to conduct research.
