An optical element comprising (i) a matrix having an Si-O covalent bond unit, wherein at least part of the silicon atoms of said Si-O covalent bond unit is covalently bonded to an aliphatic hydrocarbon group containing not more than 4 carbon atoms, and (ii) at least one functional material selected from the group consisting of an organic material showing a nonlinear optical effect, a material showing a refractive index-regulating action, and an organic dye for laser oscillation, said functional material being present within said matrix. A functional group is stably held in the matrix and fully manifests its function in the matrix.
