PROBLEM TO BE SOLVED: To provide an optical waveguide system that has a coupling mechanism capable of selecting a wavelength and has the highest possible conversion efficiency, and that is capable of providing directivity in the light propagation direction. SOLUTION: The optical waveguide system includes: a three-dimensional photonic crystalline structure 2 having a hollow structure inside thereof; an optical waveguide 4 in which a plurality of metal nanoparticles 6 are dispersed in a dielectric material 5, the optical waveguide having an end portion 4a inserted between the crystal pillars of the three-dimensional photonic crystalline structure, and containing semiconductor quantum dots 8 that are located adjacent to the metal nanoparticles and emit near-field light when receiving excitation light; and an excitation light source 10 that emits the excitation light for exciting the semiconductor quantum dots. Surface plasmon is excited when the metallic nanoparticles receive the near field light. COPYRIGHT: (C)2010,JPO&INPIT |
