Application of Full-Wave Electromagnetic Solvers to Micro/Nano-structured Fibres

The progress of full-field electromagnetic tools coupled to increasingly powerful computing hardware offer the possibility of modelling accurately micro/nano-structured fibres. Together with the advances in fabrication methods, this opens the door to the realization of optimized designs with growing complexity. Three examples of simulations are presented here to illustrate the application of general-purpose electromagnetic solvers to the analysis of micro/nano-structured fibres. Using appropriate numerical tools, the mode propagation in a fibre, the optimised coupling into a fibre from an incident field distribution, and the near-field diffraction patterns from a fibre tip can be characterized.
