<p>PROBLEM TO BE SOLVED: To provide a nonlinear optical element, having nonlinear optical characteristics utilizable for optical communication and information processing. SOLUTION: A titanium oxide layer 12 is formed divided 15 times on a substrate 10, and the titanium oxide layer is sintered at 550 deg.C. After the surface of the resultant titanium oxide layer is treated with H2O2 or ethanol, the resultant titanium oxide layer is immersed in a gold particulates dispersed solution to form a gold particulates layer 14 which consists of a single layer of gold particulates, having 2 nm to nm particle diameter. From three to ten pairs of the titanium oxide layer 12 and the gold particulates layer 14 are formed to obtain the nonlinear optical element. Since a gold particulates content in the laminated layer is high, the nonlinear optical element having the nonlinear optical characteristics utilizable for the optical communication and the information processing can be obtained.</p> |
