The imaginary-distance method is applied to an improved finite-difference beam propagation method (IFD-BPM) based on the generalized Douglas method in order to carry out eigenvalue analysis of an optical waveguide. First, we formulate the IFD-BPM to include the polarization dependence. The imaginary

We in¨estigate the numerical instability of a finitedifference beam-propagation formulation applied to tapered optical wa¨eguides, and we find that instability may occur with the use of con¨entional transparent boundary conditions. We suggest modified transparent boundary conditions to remo¨e the in
Periodic microbend losses in single-mode optical fibers are modeled here Ε½ . by using the finite difference beam propagation method FD-BPM . To reduce computational demands, the sinusoidal microbending deformation is approximated as a series of constant curvature bends of alternating sign. The spect
