Some key technologies for surface plasmon-device integrated circuits have been researched and developed to break through the integration density of OEICs, and then to support and enhance the present information society. As results, a whispering gallery mode modulator, an optical detector using localized surface plasmon resonance on the Schottky junction, a light wave-surface plsmon convertor using nano slits, a surface plsmon detector integrated MOSFET circuits were developed in this study. In addition, transmission properties of surface plasmon along the surface of metal film have been also examined, and it was clarified that the coherency of surface plasmon was kept constant during propagation of surface plasmon, although the intensity decreased due to ohmic loss. These developed techniques will be very important to develop some surface plasmon integrated circuits in future.
