The remarkable progress in spatial resolution of near-field scanning optical microscopy offers the possibility of unique interactions between light and matter at the nanoscale. In this chapter, we describe the development of a high-resolution near-field scanning optical microscope with a carefully designed aperture probe and near-field imaging spectroscopy of quantum confined systems. Thanks to a spatial resolution as high as 10–30 nm, we successfully visualize spatial profiles of local density of states and wavefunctions of electrons (excitons) confined in semiconductor quantum dots. Fundamental aspects of localized and delocalized electrons in interface and alloy disorder systems are also clarified through spatial and energy-resolved spectroscopy.
