Abstract

Nonlinear optical meterials are required for a variety of potential Air Force applications including optical signal processing (switches, modulators, and guided wave devices), and new laser sources (optical parametric oscillaotrs and harmonic generators). However, presently available materials are unsatisfacotry for many applications due to small nonlinearities, poor optical clarity, long response times, difficulty in processing for devvices, and other factors. Proposed efforts address which molecular chromphore constituents have been aligned with a storng electric field (poled) represent a promising approach to materials with large second-order optical nonlinearities. Such material combine the processability, mechanical strenght, and typically excellent transparency characteristics of glassy organic polymers with the almost infinite molecular tailorability and gigh innovative techniques for preparing new materials or for improving the growth or processing of known materials will be investigated. NLO materials devleoped in the Northwestern University is in high demand and will be synthesized for industiral applications. Nonlinear optical materials will be examined only for the prupose of evaluating and demonstrating the properities of the material(s). Phase I of this program demonstrated the proposed growth or processing techniques and potential applications. This Phase II will develop advanced nonlinear materials and relevant processes to demonstarte potential. In Phase III, advanced nonlinear optical materials will be optimized for specific applications.
