On-plane and Off-plane Metasurface Holograms
Speaker Prof. Byoungho Lee, Seoul National University
Date 20 April 2018 (Friday)
Time 10:30 - 12:00
Venue Lecture Theatre H (Lifts 27-28), HKUST

In this talk, I will discuss the methods of modulating both amplitude and phase of light or plasmonic waves using subwavelength nanostructures. These metasurfaces can independently modulate amplitude and phase of the waves and hence, provide arbitrary patterens such as plasmonic vortices, on-plane plasmonic caustics patterns and off-plane holograms. I will also describe a potential application of metasurface lenses.


Byoungho Lee received his Ph.D. degree from UC Berkeley in EECS in 1993. Since September 1994, he has been with the School of Electrical and Computer Engineering, Seoul National University, Korea. Prof. Lee is currently the Head of the department. Prof. Lee is a Fellow of OSA, SPIE and IEEE and a Member of the Korean Academy of Science and Technology and a Senior Member of the National Academy of Engineering of Korea. He has served on the Board of Directors of the Optical Society (OSA). Curretly, he is the President-Elect of the Optical Society of Korea. He has received several distinguished awards such as Jinbojang National Medal of Science. His research fields are metasurfaces, 3D imaging and augmented reality devices.
