Abstract :
A novel photonic crystal fiber (PCF) with a single core, rather than two cores, for wavelength splitting application has been proposed through the full-vector finite-element method. The light located in the 1.31- and 1.55- μm bands propagates through orthogonal polarization states in the proposed fiber. For a propagation distance of 20 mm, the 20-dB bandwidth for the same x- or y-polarized modes within the 1.31- and 1.55- μm wavelength bands could, respectively, reach 20.5 and 45.3 nm, which is much wider than that of a two-core PCF.
