Abstract
Very recent advances in the design, synthesis, and processing of nonlinear optical polymers for second-order and third-order devices are presented. Second-order polymers are now competitive with oxide crystals, and device performance has been demonstrated. Significant advances have been made in ladder polymers for third order, nonresonant devices as a result of fundamental theory and experiment. Transparent, optical quality films are reported with broadband femtosecond response and χ(3) approaching 10-7 esu. Resonant third-order polymers witn n2 comparable to AlGaAs multi-quantum well structures (MQW) have been predicted by theory, synthesized, and thin film etalons constructed and tested.
