Abstract

An analytical model for the quadratic electro-optic effect in the PLZT ceramics of the transverse modulator is presented in this paper. From the exact solutions to the electric field and the capacitance of both the single-sided and double-sided surface electrode structures derived by the conformal mapping method, the characters of transverse modulator including the half-wave voltage, switching energy and modulation uniformity for these two electrode structures are calculated for the selection of the electrode geometry. The double-sided electrodes have advantages in half-wave voltage, switching energy and the modulation uniformity over the single-sided electrodes.
