The aim of this paper is to introduce a method for enhancing the nonlinear optical properties in silica glass by using metallic nanoparticles. First, the T-matrix method is developed to calculate the effective dielectric constant for the compound of silica glass and metallic nanoparticles, both of which possess nonlinear dielectric constants. In the 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 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 compared to that of copper and gold. Further, it is found that spherical nanoparticles exhibit greater figure-of-merit compared to those with cylindrical or ellipsoidal geometries.

The principal difference in the origin of high-order optical nonlinearities caused by metallic nanoparticles embedded destructively in oxide-and chalcogenide-type glassy matrices is justified from the viewpoint of a chemical-bond approach. The numerical x-criterion is introduced to describe this difference in terms of energetic barrier between the mean molar bond energies character for inner chemical interaction of destructed components of a host glassy matrix and guest implanted atoms such as Cu, Ag, and Au. It is confirmed that destructive clustering of metallic nanoparticles is possible in hard dielectric media like oxide glasses possessing a strong negative x-criterion.
