An interpenetrating polymer network (IPN) incorporating nonlinear optical (NLO) chromophores as a second order NLO material is reported. The IPN system consists of an NLO active epoxy-based polymer network and an NLO active phenoxy-silicon polymer network. The IPN structure was characterized by infrared spectroscopy. The optical quality of the polymer film did not deteriorate after curing and poling at 200 {degrees}C for 1 h. The sample showed no decay of second harmonic intensity after being heated at 110 {degrees}C for 168 h. The nonlinear optical coefficient (d{sub 33}) of the poled IPN sample was measured to be 16.0 pm/V at 1064 nm. The high rigidity of the polymer backbones, crosslinked matrices, and interpenetration of the polymer networks are responsible for the excellent temporal stability of the second order NLO properties of the IPN system.
