ABSTRACT OF THE DISCLOSURE Optical component based on Langmuir-Blodgett layers An optical component comprises an electromagnetic radiation-transparent polymeric medium having a second- order susceptibility of at least 10-9 electrostatic units where this polymeric medium comprises compounds having polar-aligned noncentrosymmetric molecular dipoles which have as structural element an electron acceptor which is bound to an electron donor via a conjugated .pi.-electron system, which makes possible an oscillation of the molecular dipole between a ground state having a first dipole moment and an electronically excited state having a second dipole moment different from the first, and the nonionic polymeric medium comprises an alternating arrangement of at least one Langmuir-Blodgett film each of at least two different nonionic polymers having nonlinear optical properties Besides high mechanical and chemical stability the optical component of the invention has excellent non- linear optical properties, for example frequency- doubling
