Temperature stability of the electro-optic response of highly fluorinated side chain organic copolymers.

Résumé

In this work were investigated the second order nonlinear optical properties of a group of disperse red 1 based electro-optic fluorianted copolymers, synthesized with two fluorinated monomers : the a-fluoroacrylate monomer bearing the 2,2,2-trifluoroethyl side group and the a-fluoroacrylate monomer bearing the Disperse Red 1 chromophore. By means of nonlinear ellipsometry at l = 1550 nm, the poling-induced electro-optic tensor main component r33 was retrieved and the stability of the second order nonlinear properties were measured giving a depolarization temperature Tdep = 114°C and an activation energy EA » 60 kcal/mol.
