Abstract

Nonlinear polymers have Pockets’ constants exceeding that of LiNbO₃, low dielectric constants of approximately 3.0, and loss tangents less than 0.02 from dc to 40 GHz. These polymers may be spin coated to form thin films and lithographically patterned to form optical waveguides. The films exhibit good metal adhesion for electrode definition. The polymers, developed over the past five years, are now being used as the active core materials for the construction of integrated electro-optical devices such as modulators or crossbars for which the above properties should lead to high-bandwidth and low-power requirements.
