Process for producing polymeric media exhibiting third order nonlinear optical response

摘要

This invention provides a process for producing a transparent optical medium consisting of a liquid crystalline polymer which exhibits third order nonlinear optical response. Illustrative of an invention optical medium is a transparent film of a side chain liquid crystalline polymer corresponding to the formula: <IMAGE> The transparent film has an isotropic molecular configuration with macroscopic centrosymmetry, and exhibits essentially no scattering of a transmitted incident light beam.
