Optical Properties of Super-Resolution Near-Field Structure for Optical Nano-Storage

Super-resolution near-field multilayer structure can overcome the diffraction limit and promote optical nano-storage, is regarded as a promising scheme for mass storage and becomes a hotspot n nano-photonics. The super resolution is realized by the nonlinear local optical effect in the nano-film irradiated by laser. The principle how the super-resolution near-field multilayer structure overcomes the diffraction limit is introduced. The latest research progress on the important optical properties of the super-resolution nano-film, such as surface plasmon excitation. nonlinear opticat property, near-field optical property and superlens effect, is extensively studled.
