In this work were investigated the second order nonlinear optical properties of a group of Disperse Red 1 based electro-optic fluorinated copolymers, synthesized with two fluorinated monomers: the α- fluoroacrylate monomer bearing the 2,2,2-trifluoroethyl side group and the α-fluoroacrylate monomer bearing the Disperse Red 1 chromophore. By means of nonlinear ellipsometry at λ= 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 E A≈60 kcal/mol.

Abstract
In this work were investigated the second order nonlinear optical properties of a group of Disperse Red 1 based electro-optic fluorinated copolymers, synthesized with two fluorinated monomers: the α- fluoroacrylate monomer bearing the 2,2,2-trifluoroethyl side group and the α-fluoroacrylate monomer bearing the Disperse Red 1 chromophore. By means of nonlinear ellipsometry at λ= 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 E A≈60 kcal/mol.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
