Abstract

Conjugated polymers, for example polydiacetylenes and polythiophenes, possess a relatively large nonlinear refractive index together with an ultrafast relaxation time of this nonlinearity. In the infrared wavelength regions interesting for optical communication they show enhanced response due to multi-photon resonances. By comparing optically similar, but chemically different materials qualitative structure-properties relations can be derived with a view to improving the material response. Using conventional thin film deposition techniques known from microelectronics optical waveguiding structures can be fabricated, leading to the development of polymeric all- optical switching devices.
