![]() The 2D computational domain is shown in Figure 1. ![]() This assumption removes all the ∂/ ∂ y derivatives from Maxwell’sĮquations and splits them into two (TE and TM) independent sets of equations. ![]() The Y-direction is assumed toīe infinite. The FDTD approach is based on a direct numerical solution of the time-dependent Semiconductors) to be used in a typical device design. A sub-micron scale implies a high degree of light confinement andĬorrespondingly, the large refractive index difference of the materials (mostly Powerful simulation and analysis of sub-micron devices with very fine structuralĭetails. It can also model materialĪnisotropy and dispersion without any pre-assumption of field behavior such as the This is due to its uniqueĬombination of features, such as the ability to model light propagation, scattering andĭiffraction, and reflection and polarization effects. Tool for integrated and diffractive optics device simulations. The FDTD method has been established as a powerful engineering The OptiFDTD software package is based on the finite-difference time-domain OptiFDTD is a powerful, highly integrated, user-friendly software that allows computerĪided design and simulation of advanced passive photonic components.
