ORC Seminars 2011

Speaker:  Professor Din Ping Tsai, Department of Physics, National Taiwan University

Date:  10 August 2011

Time:  9.30am-10.15am

Venue:  Building 53, room 4025

Abstract: 

Progress of our current fabrication of metamaterials will be reported. Fabrication of nano bumps and 375375 vertical U-shape nano gold rings (110 nm x 60 nm x 40 nm) on a fused silica substrate has been successfully implemented by laser and e-beam lithography double exposure process separately. Light manipulation by the nanobumps and U-shape nano gold rings, and the plasmonic resonance of those particles are investigated by finite-element simulations and optical measurements, which are in excellent agreement with each other. The progress of toroidal metamaterials will be discussed as well.

Biography:

Din Ping Tsai received his Ph.D degree in Physics from University of Cincinnati in 1990. From 1990 to 1991 he was a Member of Research Staff at Micro Lithography Inc., California. He was a Postdoctoral Fellow at Ontario Laser and Lightwave Research Center, Toronto from 1991 to 1994. From 1994 to 1999 he was an Associate Professor at National Chung Cheng University, Taiwan. He joined National Taiwan University (NTU) as an Associate Professor in 1999, and became Professor and Distinguished Professor of Department of Physics at NTU in 2001 and 2006, respectively. He was invited to join Research Center for Applied Sciences, Academia Sinica as an Adjunct Research Fellow in 2006. Since 2008 he serves as the Director General of the National Instrument Technology Research Center located in Hsinchu Science Park (Taiwan). Prof. Tsai is author and co-author of 162 SCI journal papers, 42 book chapters and conference papers, and 38 technical reports and articles. He has also 18 international patents; three of which have been licensed to the world's largest optical disk manufacture company, Ritek. He had seven technologies transferred to industrial companies in last seven years. His current research interests are in nano-photonics, near-field optics, plasmonics, meta-materials, bio-photonics and their applications. Prof. Tsai is the chief  editor of "Taiwan Nano Newsletters" and "Optical Engineering" in Taiwan. He also serves on the editorial boards of "Optics Communications," "Plasmonics,"  "JEOS Rapid Publication," & "Optoelectronics Letters".
