Siloxane-silica nanocomposites functionalized with Red 17 were synthesized via a sol-gel process. Thin films were thermally cured and poled to obtain high and stable nonlinear second-order coefficients of the order of 150 to 200 pm V-1 (? = 1.064 ?m). Radiated second- harmonic generation was observed in these planar waveguides with a conversion efficiency of 5.10 -4% W-1 cm-1.
