Photonic crystals - from research to marketplace

Summary form only given, as follows. Our Photonics Group in NICHe, Tohoku University, is unique in Japanese Universities in several points: . In NICHe, I am engaged in: (1) Research activity of photonic crystals ranging from basic electromagnetic theory to practical applications. I gave an invited talk on photonic crystals in this conference. It covers my work in the research phase. (2) Pre-Venture project sponsored by Japan Science and Technology Association (JST). The aim of the project is to help university people to start up a high-tech company exploiting the strength of each team. In this rump session, I focus on what we are doing and will do during/after the "pre-venture" project.
