Abstract

The finite-difference vector beam propagation method (FD-VBPM) is applied to optical guided-wave devices based on two-dimensional directional couplers. The FD-VBPM is first validated for a parallel coupler made of two identical step-index slab waveguides by comparing with the exact analytical solutions. Subsequently, the polarization beamsplitters and wavelength filters based on directional couplers are simulated. The polarization properties of these devices are examined
