Abstract:

This report contains experimental results on a comprehensive study of the second order nonlinear optical NLO properties of a molecularly doped polymer system. A second-order NLO chromophore, 4-morpholino-4nitrostilbene MNS was synthesized which possesses a large molecular first hyperpolarizability and dipole moment. The chromophore was doped into a polymer matrix with a high glass transition temperature and subsequently poled by a strong electric field to induce noncentrosymmetry required for second-order nonlinear optical behavior. An in situ poling technique was employed to determine the processing and poling parameters in order to obtain high and stable nonlinearities. Detailed information on the synthesis, processing, characterization, and results on a series of samples is presented. Materials, Second order nonlinear optical materials, Nonlinear optics
