The ever-growing demand of high-speed information technology leads to the birth of photonic crystals (PhCs) with which one can control photons whose role in photonics is like that of electrons in electronics, giving a way to promote the speed of information transmission and processing. PhCs are materials that can serve as platforms for all devices for millimeter wave and microwave circuits as well as optical integrated circuits, e.g., waveguides, cavities, mirrors, filters, antennae, lasers, modulators, demodulators, switches, frequency converters, polarization converters, circulators, isolators, optical diodes, optical transistors, power dividers / combiners, and logic devices. So, PhCs can bring human society a novel photonic information age. This talk will provide a guidance to students and researchers about the basic concepts of PhCs, basic theoretical methods for investigations of PhCs, basic methods for fabrication of PhCs, and various applications or devices based on PhCs.

Professor Zhengbiao Ouyang received his BSc degree in radio engineering from Harbin Institute of Technology, Harbin, China, in 1983 and obtained his PhD in electron physics from the University of Electronic Science and Technology of China in 1988. He obtained the German Humboldt-von-Alexander Fellowship in 1991. He is currently a full professor in College of Physics and Optoelectronic Engineering of Shenzhen University, Director of Solid-State Photonics Laboratory, Deputy Director of THz Technical Research Center of Shenzhen University, and Vice Director of Shenzhen Key Laboratory of Micro-Nano Photonic Information Technology, a Trustee of the Chinese Society of Optical Engineering, and a senior member of the Optical Society of America. His main interests in recent years include nanophotonic materials, nanophotonic devices, high-speed optical communication technology, and THz technology. Prof. Ouyang has published more than 200 scientific papers. He holds over 70 Chinese patents of invention and over 30 US patents of invention.
