ABSTRACT:
A multi-layer Langmuir-Blodgett film having non-linear optical properties is described. Alternate layers of the film are composed of first and second elongate chromophore molecules extending transverse to the plane of the film in a Y-configuration. The molecules are sythesised so that when deposited in a Y-configuration they are non-centrosymmetric and therefore exhibit significant optical nonlinearity.
