An optical article is disclosed comprised of an organic layer unit exhibiting a second order polarization susceptibility greater than 10-9 esu and means for providing an optical input to and an optical output from the layer unit. The organic layer unit exhibits a transmission attenuation of less than 2 dB/cm and is comprised of a Y type Langmuir-Blodgett assembly having superimposed oriented monomolecular layers of first and second polymeric amphiphiles each containing repeating units comprised of a hydrophilic moiety and a lipophilic moiety. Repeating units of one or both of the first and second amphiphiles each contain an organic molecular dipole, and repeating units of one or both of the first and second amphiphiles each contains a branched lipophilic moiety of up to 9 carbon atoms.
