Abstract : The linear optical and second order nonlinear optical (NLO) properties of an interpenetrating polymer network (IPN) have been investigated. For the poled and cured IPN samples, large second order NLO coefficients, d33, were measured at 1.064 um and 1.542 um. The linear electrooptic coefficients, r33, were determined at various wavelengths. The poled and cured IPN samples showed no measurable decay of the second-order optical nonlinearity after being treated at 110 deg C for more than 1000 hours. This excellent long-term stability of the NLO property is ascribed to the novel interpenetrating crosslinked molecular structure of the IPN system.
