Title: Tunable Liquid Crystal Optical Devices
Abstract: In this talk, I will present our lab’s progress over the past decade in developing tunable liquid crystal optical devices. Key topics include: (1) cholesteric liquid crystal-based devices with broadband reflection and bistable switching; (2) Berry phase elements realized through photoalignment techniques for precise optical control; and (3) integration of liquid crystals with passive silicon photonics to enable actively tunable components. These advances demonstrate the versatility of liquid crystals in emerging photonic applications.
About the Speaker: Dr. Chun-Ta Wang earned his Ph.D. from the Department of Photonics at NSYSU in 2012, specializing in liquid crystal materials science. After completing his doctorate, he worked as a postdoctoral researcher at NSYSU from 2012 to 2015, during which he initiated research on silicon photonics. From 2016 to 2017, he was a visiting scholar at Ghent University in Belgium. Subsequently, from 2017 to 2018, he served as a visiting scholar at the Hong Kong University of Science and Technology. In September 2018, Dr. Chun-Ta Wang joined the Department of Photonics at NSYSU as a faculty member. His research primarily focuses on liquid crystal optics and silicon photonics.
