Abstract
After briefly introducing a modified Perot Fabry technique which enables to differentiate the true purely electronic Pockel effect from the piezoelectric induced electro-optic effect, we discuss the Electro Optical (EO) properties of a thermoplastic polymer and of a bismaleimide- based crosslinked network. Both polymers have large EO coefficients. However, the ratio R equals r33 / r13 is greater than predicted by the isotropic model. Values as high as 6.5 are observed in the crosslinked network. In the case of the thermoplastic polymer, the stability of the oriented chromophore is good up to 100$DEGC and disorientation is fitted reasonably well with a stretched exponential.
