Abstract
A nonlinear optical material which exhibits large third order nonlinear optical susceptibilities, and responds to light with wavelengths different from each other for multiple signal processing, and methods of manufacturing the same. This is accomplished by dispersing a high concentration of a metal fine particle and/or a semiconductor fine particle different in absorption wavelength throughout an optically transparent matrix such as a glass, a ceramic or a polymer.
