Abstract

Engineering nanohybrid polymer for photonics with emphasis on challenges in materials and opportunities will be discussed in this talk. Size- and concentration-dependent of nanoparticles and its Rayleigh scattering properties are the main point in preparing high quality and high refractive index nanohybrid polymer materials. Transparent TiO2 nanohybrid polymer is a very important material in photonics applications. Here, I will explain some simple techniques to prepare such photonics materials, and utilize Rayleigh scattering technique measured at different wavelengths to estimate the size of the nanoparticle and determine the number of nanoparticles per unit volume or particle density. Finally, the applications of these nanohybrid polymer materials especially related to the fabrication of double layer anti-reflective coating and multilayer optical interference filter will be presented.

Who is the guest lecturer?

Dr. Hendry Izaac Elim is an experimental physicist specializing in the newly emerging fields of ultrafast, nonlinear optics, and optical limiting of novel nanomaterials. This field has a great nanotechnology application to all-optical switching devices and optical limiter. He has been a research assistant professor at Tohoku University, Japan since 2007. He obtained his Ph.D. at National University of Singapore (NUS) on the fundamental　properties of nonlinear optics and optical limiting of various nanomaterials such as carbon nanotubes, fullerene derivatives, and other nanohybrid materials. His Ph.D. work has helped to clarify many fundamental nonlinear optical properties of such novel nanomaterials and resulted in a number of highly cited　publications. Before Dr. Elim finished his Ph.D, he worked as a research fellow in Department of Chemical and Biomolecular Engineering, Faculty of Engineering, NUS. He also worked for 2 years as post-doc in Physics Dept. of NUS before joining the Institute of Multidisciplinary Research for Advanced Materials (IMRAM), Tohoku University. At IMRAM, he takes part in the pioneering experiments on hybrid organic-inorganic materials, a recently developed field with various applications related to low loss optical waveguide and optical communication devices.
