Introduction

The CUDOS MOF Utilities are a software package for simulating microstructured optical fibres (or MOFs, also known as photonic crystal fibres or holey fibres) using the mutipole method [1, 2], in a Microsoft Windows environment. The software has been designed to be easy to use and can be downloaded for free from the internet [3]. Usage of the CUDOS MOF Utilities is restricted to non-commercial research and teaching purposes, as detailed in the user-licence. The package comprises two executables, fibre.exe (or Fibre ), winfield.exe (Winfield) and bfld.exe (or batchfield).

Fibre is a console based application for finding MOF modes and computing their dispersion curves, using simple macro-language based parameter files. It can deal with MOFs with circular inclusions in a circular matrix which may be surrounded by a jacket or a cladding and a jacket. Its use is described in section 2.

Winfield is a window based software for computing and visualising modal fields and derived quantities once the modes have been found with FIBRE. Its use is described here.

Batchfield is a console based application for computing the modal fields and derived quantities once the modes have been found with FIBRE. Its use is described here.
