Paper Abstract

Approaches to reduce propagation loss in polymer waveguides for passive and active applications are discussed and demonstrated. Contrary to inorganic waveguide materials, the light loss in polymer waveguides is predominantly due to intrinsic absorption processes. In the telecommunication windows in the near-IR the absorption is due to vibrational overtones. The light loss can be decreased by reduction of the concentration of C-H, N-H and O-H groups in the polymers. Edge absorption by electronic transitions of charge transfer bands of nonlinear sidegroups in electro-optic polymers does not contribute to light loss in this region.
