## Light propagation in optical waveguides is studied in the paraxial approximation using Richardson extrapolation and the mid-step Euler finite difference algorithm. Highly accurate solutions can be efficiently obtained using this combined approach. Since discretization errors in both the transv

## Abstract Richardson extrapolation is a methodology for improving the order of accuracy of numerical solutions that involve the use of a discretization size __h__. By combining the results from numerical solutions using a sequence of related discretization sizes, the leading order error terms can
A FORTRAN-77 program is presented which solves the Sturm-Liouville problem for a system of coupled second-order differential equations by the finite difference method of the seco~idorder using the iterative Richardson extrapolation of the difference eigensolutions on a sequence of doubly condensed m
