ABSTRACT
As a promising disk structure for ultrahigh density optical data storage, super-resolution near-field structure of AgO[sub x] type has been studied by the tapping-mode tuning-fork near-field scanning optical microscope as well as the transmission electron microscope. This structure presents strong near-field intensity enhancement and nonlinear optical effect, compared with the ordinary material. Numerical calculations confirm that the localized surface plasmon and the nonuniform material structures are the main causes for these unusual characteristics. © 2001 American Institute of Physics.
