It is well recognized that Vycor brand porous glass impregnated with a photosensitive organometallic compound can be used to produce refractive index patterns upon photolysis [1–3]. For instance, a metal carbonyl such as Mn2(CO)10 adsorbed into the porous glass matrix has been used to photopattern high resolution phase gratings albeit with low diffraction efficiencies due to the low refractive index change (Δn) so produced [1].
