A novel structure of large-mode-area photonic crystal fiber (LMA-PCF) with elliptical air hole is proposed and investigated in this paper. The design of the novel photonic crystal fiber works on the principle of bend-induced mode filtering. On this basis, the idea of using the new parameters of the eccentricity of the ellipse to control the bending losses of the fundamental and first higher order modes was proposed. The fiber structure proposed in this paper has the potential to be applied to compact high-power delivery devices, which is of great significance for high-power laser systems and optical amplifiers..
