Abstract :
The finite element method (FEM) is used to model a titanium (Ti)-diffused lithium niobate (LiNbO3) electro-optic modulator. The more important parameters of the modulator, such as the refractive index profile, the optical field profile, the applied electric field profile and the overlap between the applied electric and optical fields for a variety of electrode positions are included in this model. By adjusting the position of the electrodes, it is possible to obtain the maximum value of the overlap
