Abstract
Modal dispersion phase-matched second harmonic generation is demonstra ted in new poled polymer waveguide geometries with a nonlinear optical core consisting of two side-chain polymers with different glass trans ition temperatures. After poling above and between the respective glas s transitions, the sign of the nonlinear optical coefficient is revers ed in the two polymers, thereby improving the overlap integral. Conver sion efficiencies up to 7%/W cm(2) were achieved in the first experime nts. (C) 1997 American Institute of Physics.
