Modal dispersion phase-matched second harmonic generation is demonstrated in new polymer waveguides with a nonlinear optical core consisting of two side-chain polymers with different glass-transition temperatures. After poling above and between the respective glass-transitions, the sign of the nonlinear optical coefficient is different in the two polymers, thereby improving the overlap integral. Large conversion efficiencies up to 7%/Wcm2 were achieved in first experiments.
