dc.description.abstract In this paper we have designed a model of hexagonal photonic crystal fiber (HPCF) where we changed the parameters- diameter of air hole d, pitch A to observe the effect on propertise of photonic crystal fiber (PCF). Using comsol multiphysic 4.3b we have designed a five ringes HPCF with the finite elememt method and with boundary condition perfectly mathed absorbing layers (PML to investigate the guidling properties. It is considered to be the most efficient boundary condition for the PCF simulation. At first we kept the pitch constant and varied the diameter of the air hole and saw the effect on effect mode index Deff, effective area Aeff, confinement lossand chromatic dispersion D. Similarly, we changed the value of pitch keeping the diameter of the air hole constant. For dispersion compensating fiber in communication system we required negative dispersion at 1.55 Jlm wavelength, this is because at 1.55 pm wavelength we have minimum attenuation. Through our research we observed that for value of pitch 1\1= 0.8 Jlm and air hole diameter d= 0.38 Jlm, we get negative chromatic dispersion value approximately around -1205 pslnm!km for 1.55 Jlm wavelength. This proposed HPCF is used for dispersion compensating fiber in communication system en_US
