Paper Abstract

A wide range of photonic guided-wave devices may be modelled by using rigorous numerical approaches based on the finite element method (FEM). In this work, representative modal solutions for linear, nonlinear, anisotropic, passive and active waveguides are discussed. Photonic devices incorporating several butt-coupled uniform waveguide sections, such as optical modulators, switches, filters, polarizers, and duplexers, are shown by incorporating the least squares boundary residual (LSBR) method and the FEM. The FEM-based beam propagation method (BPM) is used to characterize photonic devices incorporating arbitrarily nonuniform guided wave sections or optical devices with second and third order material nonlinearity.
