Welcome to Nano Photonics Laboratory

Welcome to the web page of Nanophotonics reseach group at Kongju National University! The group is headed by Jin-Kyu Yang, a professor in Dept. of Optical Engineering. Our research is focused on the interaction of photons with periodic or non-periodic structures on the scale of an optical wavelength. Various artificially-controllable photonic resonant structures are under investigation. Research topics are categorized into two parts. The one is about dielectric photonic structures underlying two-dimensional periodicity or quasi-periodicity The other is about meta-materials based on metallic subwavelength geometry.

I hope this web page give you useful information, and please have fun! More information, or news about our group please also visit our wiki.
