学术报告--Development of Bi/Er Optical Fibres for Ultra Broadband Emission

时间:1月18日(本周五)下午三点
地点:澳门皇冠金沙网站4楼报告厅
    In this talk I will present our recent work on the first development of a Bi/Er/Al/P co-doped germanosilica optical fiber showing ultra broadband luminescence between 1000 and 1570 nm, covering O-, E-, S-, C- and L-bands, when pumped by 532, 808 or 980 nm lasers. The fluorescence profiles are found highly pump wavelength dependent, closely associated with different combinations of excitations from both Bi centres and Er ions as active centers. With a proper selection of pump wavelength(s), this Bi/Er codoped fiber could be used as an ultra broadband gain medium for ultra broadband band ASE sources, fiber lasers or amplifiers in telecommunications, and other fields.
 
Biography
    Gang Ding Peng received the B.Sc. degree in physics from Fudan University, Shanghai, China, in 1982, and the M.Sc degree in applied physics and the Ph.D. degree in electronic engineering from Shanghai Jiao Tong University, Shanghai, China, in 1984 and 1987, respectively. From 1987 through 1988 he was a lecturer of the Jiao Tong University. He was a postdoctoral research fellow in the Optical Sciences Centre of the Australian National University, Canberra, from 1988-1991. He has been working with University of NSW in Sydney, Australia since 1991, was a Queen Elizabeth II Fellow from 1992-1996 and is currently a Professor in the same university. He is a fellow and a life member of both OSA and SPIE. His research interests include optical fibre and waveguide devices, silica and polymer optical fibres, optical fibre sensors and nonlinear optics.
