Outline of Final Research Achievements

Introducing nano-structure can enhance an original function of a material. Composite structures with periodically arranged Au particles and magnetic garnet show several absorption bands excited by surface plasmon resonances in their transmissivity spectra, and they enhanced Faraday rotation angles at these wavelengths of plasmon resonance. By experiments and FDTD simulations, we examined the optical and magnetooptical properties of the structures.
In order to observe optical distribution with high resolution around the Au particles, we fabricated a scanning near-field microscope using an aperture-less probe. In addition, we developed a laser lithography system to fabricate fine pattern.
