Abstract

A Langmuir-Blodgett film comprises at least one layer of amphiphilic molecules which are of two different types. The first type comprises molecules that are active in nonlinear optics. The second type consists of molecules that are inert or active in nonlinear optics. The mixture of these two types of molecules, in specified proportions, gives a film capable of radiating, perpendicular to the substrate, an optic wave which is a second harmonic with reference to an exciting wave.
