Abstract

A fully vectorial finite difference beam propagation method for 3D waveguide structures, including longitudinally variant structures is presented. The transparent boundary conditions are utilized in the edges of the computational window. Both Gaussian beams and exact fields of the guided modes are launched as the starting field. Propagating fields are calculated and the power attenuation is evaluated. The choice of step size, finite difference scheme parameter and reference propagation constant is discussed. The applicability and accuracy are demonstrated for two particular waveguide structures.
