Abstract
A method for substantially increasing the refractive index change induced in porous glass through metal oxide deposition by photolysis of organometallic compounds present therein, according to which the photolyzed glass is re-impregnated with additional organometallic compounds which undergo decomposition reactions catalyzed by the photolyzed organometallics or oxides resulting from the initial photolysis step. Enhancements of ten times the original refractive index change are attainable.
