Abstract : The goal of Phase I was to develop high-mu-beta chromophores with low absorption loss and high bulk EO nonlinearity at 980 nm. The Phase I work focused on second-order optical nonlinearities in dipolar chromophores of the general form (electron donor)-(pi-bridge)-(electron acceptor). Six different methods of 'engineering' such material were explored. Two of the methods studied focused on improving the electron donor functional group; two focused on improving the pi-bridge architecture; and two focused on improving the electron acceptor functional group. Four showed sufficient promise to warrant further consideration in Phase II. Based on these results, we believe that the feasibility of developing a protocol for systematically designing blue-shifted chromophores with high bulk nonlinearities has been demonstrated. Moreover, by exploring not one, but several, different and promising materials systems, we have laid a solid theoretical and experimental foundation for the Phase II work, greatly improving the chances of technical and commercial success.
