Abstract By using the complex finite element method (FEM) under perfectly matched layer (PML) boundary conditions, dispersion properties of microstructured optical fibres (MOFs) with elliptical air holes are analysed by changing the pitch and sizes of air holes belonging to the inner three rings. Meanwhile, the confinement loss of the fundamental mode is engineered to achieve the single-polarization single-mode transmission. Based on this analysis, a novel design of MOFs for properties of the single-polarization single-mode and the nearly zero ultra-flattened dispersion between 1pskm-1nm-1 in the wavelength range of 1.2--1.6μm is presented for the first time.
