Hybrid near-field optical memory and photofabrication in dye-doped polymer film

A hybrid near-field fluorescence microscopy, which combines near-field scanning optical microscopy and photon scanning tunneling microscopy, is demonstrated for nanoscale optical memory and photofabrication on spin-coated dye-doped polymer films. Storage capacity and readout signal-to-noise ratio with near-field one-photon and two-photon excitations are studied.
