Paper Abstract

The dipole moments ((mu) ) of a series of zwitterionic nonlinear optical chromophores doped into poly(methyl methacrylate) have been determined. Values of between 34 D and 38 D have been measured through the fitting of a uncurtailed Langevin function to the incidence angle dependence of the p-p second harmonic intensity generated from corona poled films. It is shown that accurate values of dipole moment can only be determined when the poling fields are lower than approximately 100 MVm-1 above which existing electric field poling models appear to be inadequate. The reasons for this are as yet unknown, possible mechanisms of the effect are presented.
