Outline of Final Research Achievements

We have investigated excitation transfer via near-field optical interaction, which is generated on illuminated nanometer-scale matter. We measured excitation transfer in semiconductor quantum well with local excitation by a gold nano-rod by using a scanning near-field optical microscope, which visualizes distribution of excitation in the well. This study is essential basis for developing new devices based on near-field optical interaction.
