Abstract
In the present work, a nonlinear dielectric function is derived using the B orn-Huang equation and taking into account dispersion of optical phonons an d nonlinear terms in the polarization vector P(u, E). The theoretical resul ts show an obvious shift of the profile of the dielectric function. The sam e expressions for the linear dielectric functions as previous ones are also obtained when nonlinear factors are set to be zero in the present formulae .
