Abstract

We report our study of a new sol-gel polymer for nonlinear optics applications. An amino- sulfone dye chromophore was covalently incorporated into a sol-gel network and each chromophore was firmly anchored at both ends via nine possible crosslinking sites. After corona poling and thermal curing at elevated temperatures using a new kind of `step' poling profile, a d₃₃ of 27 pm/V was measured at the 1.06 micrometers fundamental wavelength. Long term stability at 100 degree(s)C and short term stability at 200 degree(s)C were demonstrated. A phenomenological explanation for the behavior of the dynamic SHG signal to our `step' profile is also proposed.
