Abstract
We compare results obtained from two numerical methods: (i) a local normal mode (LNM) description using modes computed by the finite-element method (FEM), and (ii) a three-dimensional beam-propagation method (BPM) for the analysis of a passive integrated-optical polarization splitter, which is, e.g., an essential element of a tunable integrated-optical wavelength multiplexer.1 By indiffusion of Ti into LiNbO3, directional couplers with large polarization sensitivity can be realized owing to the strong anisotropy of the diffusant-induced index variations.2
