Abstract

Microstructured Optical Fibres (MOF) with their flexibility of design and use of diverse materials with specific optical properties are currently of interest for many different applications. Many MOF geometries currently of active research interest are highly multimoded and can support many thousands of modes [1,2]. Often the measure of the performance of these fibres are calculated from a knowledge of the effective indices and losses of all or a significant number of the modes — for example the local density of states, bandwidth, numerical aperture, modal cutoff and number of supported modes [3]. The development of robust and efficient tools to calculate a large number of modes is becoming increasingly important as designs become more sophisticated.
