An optical article for the propagation of electromagnetic radiation is disclosed comprised of an electrically conductive support on which a poled polymeric film exhibiting a glass transition temperature of at least 80.degree. C. and a second order polarization susceptibility greater than 10.sup.-9 electrostatic units is formed. A layer for enhancing the transmission of electromagnetic radiation is interposed between the electrically conductive support and the poled polymeric film. The transmission enhancement layer is an amorphous layer of at least 0.5 .mu.m in thickness having a refractive index less than that of the polymeric film and a resistance less than 10 times that of the polymeric film. The transmission enhancement layer being comprised of a mixture of (a) at least one metal oxide or fluoride and (b) a low molecular weight aromatic compound.

Nonlinear optical article with improved buffer layer

An optical article is disclosed containing contiguously overlying an organic layer for the nonlinear propagation of electromagnetic radiation an amorphous transmission enhancement layer of at least 0.5 .mu.m in thickness transmissive to the nonlinearly propagated electromagnetic radiation, exhibiting a refractive index less than that of the organic layer, and comprised of a low molecular weight aromatic compound.
