Fabrication method of silver nanowire array is established for optical nano-imaging. Silver nanowires have the property of optical transfer by surface plasmon resonance. We found out the array of silver nanowires act as one of the lens. Furthermore, it is useful as nano-imaging device beyond the diffraction limit, because it transfers the electric field confined to several tens of nanometer as wire diameter.In this research, I have simulated the resonant spectra depending on the wire length and wire diameter for the device fabrication. The apparatus for anode oxidization of aluminum and electro plating was developed to fabricate nanohole array in self-organization process and fill their nanoholes in silver, respectively.
