Abstract
The chromatic dispersion curve of the fundamental mode in small core microstructured fibres (SCMFs) is both calculated using a finite element method (FEM) and measured with a low coherence interferometric method. The great sensitivity of the chromatic dispersion to variations of the geometrical parameters of SCMFs (the pitch ? and the diameter d) is pointed out. Excellent agreement is obtained between the numerical and the experimental results over a half micrometre spectral bandwidth (1.1?1.6??m).
