# Application Example: Ferroelectric Modulator

#1

Calculate the performance of a ferroelectric waveguide modulator using DEVICE: Charge and FDTD Solutions.

In this example, we simulate a ferroelectric waveguide modulator which uses BaTiO2 - a material which exhibits a change in refractive index due to applied electric field. This device is based on the publication by Xiong et al.[1] We extract the effective index of the waveguide modulator versus voltage for a given operating frequency.
