We report a systematic investigation on organic-inorganic hybrid sol-gels doped with nonlinear optical chromophores. The host is based on photosensitive sol-gels prepared from precursor of 3-(methacryloxy)propyl trimethoxysilanezirconium (or aluminum) oxide (MAPTMS-Zr(Al)) hybrid system. The chromophores are incorporated into the hybrid sol-gels as both guest and side-chain. Second harmonic generation experiment has been conducted to optimize the poling parameters for the active sol-gel films and examine the stability of the second-order nonlinear optical coefficients. Electro-optic channel waveguides have been fabricated by direct ultra-violet (UV) exposure, direct blue laser writing, and reverse-mesa methods. Electro-optic effect of the waveguides is measured at 1550 nm. All the results show that the hybrid sol-gels are promising media for electro-optic devices for integrated optics in both performance and fabrication flexibility.
