摘要
We develop a beam propagation method based on full-vectorial higher-order finite-difference formulation to model optical waveguides. Simulation of a photonic crystal fiber coupler is used as assessment of different schemes and convergence behaviors. Results including error convergence and field calculation show that they are improved by using higher-order scheme.
