Paper Abstract

The near-field recording mechanism of the super resolution near-field structure, glass/ZnS-SiO2/AgOx/ZnS-SiO2, has been studied experimentally. Near-field optical effects of the glass/ZnS-SiO2/AgOx/ZnS-SiO2 have been observed by a tapping mode tuning-fork near-field scanning optical microscope (TMTF-NSOM) on the transmitting light spot. Laser-excited surface plasmon at the interfaces of AgOx/ZnS-SiO2 thin film was detected by this technique. Results showed that the transmitting focused light through the AgOx type super resolution near-field structure consists of a propagating term and an evanescent one resulted from the localized surface plasmon of the AgOx thin film. A strong enhancement of the near-field intensity and the dynamic localized enhancement of the transmitting focused light were observed as well.
