Frequency-agile, femtosecond Hyper-Rayleigh scattering measurements are used to test the utility of density functional theory calculations for suggesting chromophore structures with improved molecular first hyperpolarizability, beta. A tricyanopyrroline acceptor is shown to yield a factor of approximately three improvement over the commonly used tricyanofuran acceptor. The combination of improved chromophores and incorporation of chromophores into novel nanostructured lattices is leading to routine realization of electro-optic coefficients greater than 100 pm/V at telecommunication wavelengths. In this communication, the use of nanoimprint lithography to stamp out active and passive optical circuitry is also demonstrated. The potential for low-cost, mass production of electro-optic devices, including conformal and flexible devices, is suggested.
