- Current paper is aimed at introducing a method for enhancing the nonlinear optical properties in silica glass by using metallic nanoparticles. First, the T-matrix method is developed in order to calculate the effective dielectric constant as well as the compound of silica glass and metallic nanoparticles, both of which possessing nonlinear dielectric constants. In second step, the Maxwell-Garnett theory is exploited to replace the spherical nanoparticles with cylindrical and ellipsoidal ones, facilitating the calculation of the third-order nonlinear effective susceptibility for a degenerate four-wave mixing case. The results are followed by numerical computations for silver, copper and gold as nanoparticles. It is shown, graphically, that the maximum and minimum of the real part of the reflection coefficient for nanoparticles of silver occurs in smaller wavelengths in comparison to that of copper and gold. Further, it is found that the nanoparticles of spherical shape exhibit greater figure of merit in comparison to those with cylindrical or ellipsoidal geometries.
