Abstract

An analytical theory of dielectric and optic non-linear effects of ferroelectrics is presented in this paper. The theory includes the intrinsic relations between the ferroelectricity (P-E), dielectric nonlinear (ε-E) and optic nonlinear (△n-E) in ferroelectric materials. An analytic equation for dielectric and optic nonlinear effects of ferroelectrics is obtained, and then the simple polynomial functions of P(E), ε(E) and △n(E) are used to describe the mechanism of dielectric and optic nonlinearity. From the experimental hysteresis loop, e.g., ε-E and △n-E curves in ferroelectric materials, the boundary conditions and original conditions are obtained, and the related coefficients are also determined in the terms of Pm, Ps, Pr, EAEc, and ED. Moreover, this analytic theory is verified by the data from Ba0.9Sr0.1TiO3and PLT/PZT films.
