Abstract
There are provided a third-order nonlinear optical material comprising a film formed on the surface of a transparent substrate and consisting essentially of an oxide of a metal selected from the group consisting of V, Cr, Mn, Fe, Co, Ni and Cu; and a third-order nonlinear optical material of the type as described above wherein the film additionally contains a metal selected from the group consisting of Au, Ag and Cu in the form of particles dispersed therein and having a particle size of at most 500 nm.
Claims4
A process for producing a third-order nonlinear optical material, comprising the steps of impregnating in a porous transparent matrix a solution containing a precursor of at least one oxide of at least one metal selected from the group consisting of V, Cr, Mn, Fe, Co, Ni and Cu, drying, then calcinating the resulting transparent matrix to thereby have particles of the metal oxide having a particle size of 500 nm or below dispersed and deposited in the transparent matrix.
