Title: Preparation, optical and non-linear optical power limiting properties of Cu, CuNi nanowires

Metallic nanowires show excellent Plasmon absorption which is tunable based on its aspect ratio and alloying nature. We prepared Cu and CuNi metallic nanowires and studied its optical and nonlinear optical behavior. Optical properties of nanowires are theoretically explained using Gans theory. Nonlinear optical behavior is studied using a single beam open aperture z-scan method with the use of 5‚ÄČns Nd: YAG laser. Optical limiting is found to arise from two-photon absorption.
