Abstract

A simple algorithm for solving the finite-difference (FD) equations for the mode eigenvalues and field distributions of a linear waveguide is presented. By applying the discretized Helmholtz operator column-by-column to an index distribution defined on an NxN grid, a matrix whose size is only a few times NxN is obtained. This yields a reduction in computation time and space compared with the other classical FD approaches which involve an N²xN² matrix.Our method is tested against problems for which the exact solutions are known, and we find a high degree of accurary.
