Poling fields, theoretical models

The nonlinear response of these materials has been the subject of theoretical investigations, based on the oriented gas model. In this model it is assumed that (i) chromophores don t interact with the matrix and with each other (ii) they have cylindrical shape, are free to rotate under the influence of the poling field and have only one significant beta component, i.e. that along the molecular axis Pxxx, (iii) the permanent dipole moment of the molecule is oriented along the z axis. On this basis, a relation between the macroscopic nonlinearity of the material (i.e. r33 or r/33 coefficient) and the molecular properties of the chromophore can be deduced [2]... [Pg.100]
