Presents the most recent developments in second-order nonlinear optical polymers. Covers the most important technologies necessary to achieve commercially viable devices based on special polymeric materials with second-order nonlinear optical properties. Discusses important molecular design considerations, how to process the polymers into films, the stability of the films, their optical properties, and prototype devices that can be made from these films.

In this contribution, we describe the synthesis and second-order optical properties of a series of mixed-substituent poly(organophosphazenes)that possess covalently attached donor-acceptor substituted, conjugated moieties. The general structure of the polymer is (NP(OCH2CF3)x(OR)(y))(n), where OR = -O(CH2O) (k)C6H4-CH=CH-C6H4NO2; where k = 1-3, and -OCH2CH2N(CH2CH3)C6H4-N=N-C6H4NO2, and x + y = 100%. The nonlinear optical properties of thin films of the polymers were investigated by using second harmonic generation, giving second-harmonic coefficients, d(33), in the range 4.1-34 pm/V. (AW).

Successful development of materials for photonic applications requires an understanding of the nonlinear optical process, chemistry and processing of materials, and technologies for device fabrications. We are able to successfully use different chemistries to develop several types of crosslinked and networked systems. Significant progress in improving material properties has been accomplished. Promising results have been observed in several materials developed. A prototype frequency doubling device has been prepared; second harmonic Cerenkov radiation emitting green and blue light have been observed. Relevant chemical modifications to fine-tune or enhance the desired properties will need to be iteratively performed to obtain optimized properties for practical applications. Polymeric materials, High speed EO modulation, Second-order nonlinearity, Optical losses.
