Abstract
In this paper, the possibility of using topology optimization for tailoring the dispersion properties in optical fibres is discussed. A method for finding the sensitivities of the dispersion coefficient is introduced, along with different constraints for confining the light to the centre of the fibre geometry. The modal analysis of the fibre geometries is carried out with a finite-difference approximation to the scalar Helmholtz wave equation. The results, obtained by optimizing the refractive index distribution over the cross section of the fibre, show that it is possible to match the value of the dispersion coefficient at both a single and at multiple wavelengths.
