Abstract
Full-vectorial beam propagation methods (FVBPMs) are widely used to model light waves propagating in highindex- contrast optical waveguides. We show that the paraxial FVBPM and wide-angle FVBPMs based on diagonal Padé approximants are analytically unstable for waveguides with complex modes. The instability cannot be removed by enlarging the computational domain, increasing the numerical resolution, or using perfectly matched layers, because the complex modes are highly confined around the waveguide core. © 2011 Optical Society of America.
