Abstract
In this paper we have introduced an efficient design of photonic crystal fiber i.e. decagonal 4 ring structure with circular hole in core. Perfectly matched layer has been applied outside the cladding to prevent reflections. We have analyzed this design in COMSOL Multiphysics simulation tool. We have calculated effective refractive index and dispersion for this design by varying pitch keeping diameter constant and by varying diameter keeping pitch constant. Core is filled with glycerol and optimum values of pitch and diameter are found.
