    "abstract": "We present in this paper a method to recover the refractive index profile of\ngraded waveguide from the effective indices by cubic spline interpolation\nfunction. It is proved by numerical analysis of several typical index\ndistributions that the refractive index profile can be reconstructed closely to\nits exact profile with the presented interpolation model. This method can\nreliably retrieve index profile of both more-mode (more than 4 guiding mode)\nand fewer-mode (2-4) waveguides.",
