Nanophotonics: the breakthrough technology to control nanostructure by photons with near field and nonlinear optics

Summary form only given. The minimum size of the light spot generated with traditional optics is around a half micron. In this presentation, I will show how we can exceed this limitation due to the diffraction of the light with an evanescent photon, which has an imaginary momentum component to tunnel in the near field between nano-probe and nano-structure. Nonlinear response of the material to photon intensity can be also used for super-resolving imaging. I will show our experimental results from our developed near-field Raman imaging/spectroscopy, coherent anti-Stokes Raman microscopy, and two-photon photo-polymerization and photo-isomerization for fabrication, manipulation and observation of nano structures.
