Electro Optic simulations module

About electro-optic module:
The starting point of all optical simulations is to obtain the correct refractive index distribution of the structure. The operation principle of many planar waveguide devices is based on a small locally induced perturbation of the refractive index. To predict and optimize the optical performance of devices requires calculation of the correct refractive index perturbation to be taken into account for subsequent optical simulations.
The electro-optic (EO) module calculates the index perturbation in devices activated using an electric field applied across the waveguide region, such as LiNbO₃-based switches.

Benefits of EO module:
The (quasi-static) electric field distribution is calculated using a fast Finite Difference solver. The electro-optic coefficients of materials used are automatically incorporated for translation into the refractive index perturbation. This perturbation is again added to the index distribution of the basic structure for subsequent optical simulations using any of the mode solver or propagation modules.
