Optical FDTD Overview

OptiFDTD enables you to design, analyze and test modern passive and nonlinear photonic components for wave propagation, scattering, reflection, diffraction, polarization and nonlinear phenomena. The core program of OptiFDTD is based on the Finite-Difference Time-Domain (FDTD) algorithm with second-order numerical accuracy and the most advanced boundary conditions – Uniaxial Perfectly Matched Layer (UPML).


The algorithm solves both electric and magnetic fields in temporal and spatial domain using the full-vector differential form of Maxwell’s coupled curl equations. This allows for arbitrary model geometries and places no restriction on the material properties of the devices.
