Side-chain maleimide based electro-optic polymer for second-order nonlinear optics

Abstract:

The electro-optic properties of a poled second-order nonlinear optical maleimide polymer system were reported. This polymer was synthesized by doping disperse red 1 moieties into the maleimide system as the side chains. Its glass transition temperature was measured to be 202°C by Differential Scanning Calorimetry (DSC) technology. After being poled, the measured electro-optic coefficient of PHSD at the wavelength of 1550 nm is as large as 3. 03 pm/v. Except for an initial decay after being poled, PHSD exhibits little electro-optic relaxation in a long term and its electro-optic coefficient remains about 2. 46 pm/v after 15 days.
