We propose a new photonic crystal fiber design with a W-shaped effective index profile to achieve the largest effective area (Aeff) for telecommunication use. We realized a 220-μm2 Aeff while achieving both a cable cutoff wavelength of less than 1300 nm and a bending loss compatible with ITU-T recommendations G.655 and G. 656.
