The nonlinearity is thermally stable up to 140 °C and retains 90% of the original value even when stored at 100 °C for 100 h. The polymer has a relatively low nonlinearity (d₃₃ = 3.6 pm/V) due to the incorporation of a low β chromophore.3 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
