Abstract: A detailed modal analysis of Photonic Crystal Fiber (PCF) is carried out by using the Finite Element Method (FEM) in FEMLAB environment. The effective mode index of the fundamental mode is found out for different PCF structures and the effective mode area is calculated for varying number of air hole rings. Finally, dispersion and confinement loss properties of different PCF structures are numerically calculated and it is found that the dispersion and confinement loss profile of the PCF can be controlled by appropriately choosing diameter, pitch and number of air hole rings. The results show that the effective mode area and the confinement loss decreases with the increase in number of air hole rings and the dispersion increases with the increase in number of air hole rings.
