应我室储涛研究员邀请,英国伦敦城市大学的Azizur Rahman教授将于2016年8月23日来所交流并在黄昆半导体科学技术论坛上作第288期报告。请感兴趣的老师同学准时参加。

报告题目:Design and Optimization of Silicon Photonic Devices

报告人:Prof. Azizur Rahman,(City University London, UK)



Abstract:Silicon has been a particularly attractive material for photonics as the low-cost and mature CMOS fabrication technology widely used in the electronics industry can be exploited. The high index contrast of silicon allows light confinement in submicron size waveguides

However, strong spatial field variation and high field at the dielectric interface demands a full-vectorial approach must be used. The full-vectorial H and E-fields and the Poynting vector profiles

of the silicon waveguide are shown in detail. The modal solutions of silicon nanowires and vertical and horizontal slot waveguides will be presented. Rigorous design optimization of silicon nanowires

and slot waveguides and various guided-wave devices, such as power splitters, mode splitters, polarization splitters, polarization rotators, biosensors, SBS and spot-size converters will also be presented.

Biography: B. M. Azizur Rahman received the B.Sc.Eng and M.Sc.Eng. degrees in Electrical Engineering with distinctions from Bangladesh University of Engineering and Technology (BUET), Dhaka,

Bangladesh, in 1976 and 1979, respectively. In 1979, he was awarded with a Commonwealth Scholarship to study for a PhD degree in the UK and subsequently in 1982 received his PhD degree in

Electronics from University College London. In 1988, he joined City University, London, as a lecturer, where he is now a Professor. At City University, he leads the research group on Photonics Modelling,

specialized in the use of rigorous and full-vectorial numerical approaches to design, analyze and optimize a wide range of photonic devices, such as spot-size converters, high-speed

optical modulators, compact bend designs, power splitters, polarization splitters, polarization rotators, polarization controllers, SBS, terahertz devices, etc. He has published nearly 500 journal

and conference papers, and his journal papers have been cited more than 3200 times. He has supervised 25 students to complete their PhD degrees as their first supervisor and received

more than £8 M in research grants. Prof. Rahman is Fellow of the IEEE, Optical Society of America and the SPIE.
