Outline of Final Research Achievements

This research was performed to clarify detail of light localization in disordered materials, such as Anderson localization of light and random lasers, by high-resolution optical-imaging technique. An original home-made scanning near-field optical microscope (SNOM) was developed and successfully observed Anderson localization of light by using SNOM with an aperture probe. Furthermore, to investigate the spatial correlation between Anderson localization and random laser, a SNOM with approaching technique using tunneling current has been developed.
