Research column). They are the optical microscopy technology of analyzing material properties (example: metal and semiconductor) with nanoscale resolution (top), and the technology which controls propagation of the plasmon through nano-metallic-light-waveguides(center). These are the technologies for realizing a nano optical microscope and a nano optical integrated circuit, respectively. The technology which controls heat radiation of an object by putting a thin film which have array of a fine gold structure also is reported (SPIE Newsroom（web magazine）)(bottom). This is the technology which paves the way for recycling various heat wastes. Progress of nano photonics and plasmonics researches and industrial innovation are attracting attention.
