Abstract
This invention provides an optical medium and a process therefor wherein the medium exhibits third order nonlinear optical response and comprises a polymer with pendant groups having delocalized pi-electron character forming a charge transfer complex with dopant molecules. The optical medium is useful in optical devices, such as optical switches or light modulation devices as a component or as a coating. In other aspects, novel polymers and polymer complexes are disclosed.
