Optically non-linear materials and thin films incorporating such materials.

摘要

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 synthesised so that when deposited in a Y-configuration they are non-centrosymmetric and therefore exhibit significant optical nonlinearity.
