An evaluation of modelling of propagation using COMSOL for singlemode-multimode-singlemode structure

Date
2024
Abstract
This paper presents models developed for investigating multimode interference structures with the intention of utilising precise 3D printing to print the centre section of the structures modelled. The models allow the design of structures for use in fibre sensors, replacing the silica fibre centre section structures currently used. The paper outlines the process of evaluating and validating COMSOL propagation models by comparison to existing reported results. The proposed model shows excellent agreement in calculating self-imaging length with the other referenced models and an analytical calculation.
