We present the use of Douglas-Gunn Alternating Direction Implicit finite difference method for computationally efficient simulation electric field propagation through a wide variety optical fiber geometries. The can accommodate refractive index profiles arbitrary shape and is implemented in tool called BPM-Matlab. validate BPM-Matlab by comparing it to published experimental, numerical, theoret...

MATLAB [?] is one of the most widely used mathematical computing environments in technical computing. It is an interactive environment that provides high performance computational routines and an easy-to-use, C-like scripting language. Mathworks, the company that develops MATLAB, currently does not provide a version of MATLAB that can utilize parallel computing [?]. This has led to academic and...
