Abstract:
1. An optical device using a 3 rd order nonlinear optical phenomenon, comprising: a signal beam waveguide through which a signal beam propagates, said signal beam waveguide being formed of a nano-composite material made by dispersing metal nano-particles in a dielectric or polymer matrix of a nonlinear optical material having a large 3 a pump beam waveguide through which the pump beam propagates, said pump beam waveguide being formed of a material absorbing very little or no light in both the signal and the pump beam wavelength ranges, wherein at least a part of the pump beam waveguide is arranged adjacent to at least a part of the signal beam waveguide so that the pump beam can be coupled to the signal beam waveguide, the signal beam waveguide and the pump beam waveguide are made of different kinds of materials, and the signal beam and the pump beam are different in their wavelength regions.
