Abstract

We propose an orbital angular momentum (OAM) photonic crystal fiber (PCF) that can control the dispersion of OAM mode by using a ring-core to which a graded-index profile is applied. Using the full-vectorial finite element method (FEM), the properties of the proposed OAM PCF were analyzed. We found that when the thickness of the ring-core to which the graded-index profile was applied is reduced, the dispersions of the modes guided to the core decrease overall.
