Modeling a hexagonal periodic photonic crystal fiber for optical communication

The various optical properties like effective mode area, effective mode index, dispersion and confinement loss of chalcogenide hexagonal photonic crystal fiber (PCF) is investigated thoroughly discussed in this paper. This paper also deals with the same properties with respect to number of air hole rings. Finite difference time domain (FDTD) technique is used to find out the modal distribution of the aforesaid PCF. Using this technique, a linear variation of both effective mode index and effective mode area are observed. Similarly an interesting result is also revealed in case of dispersion and confinement loss with respect to number of air hole rings and wavelength.
