Photonic crystal fibers with ultra low confinement loss and anomolous dispersion behavior

This paper presents propagation characteristics of three different hexagonal PCF structures which have different d / Λ ratio. It has been observed that PCF structure with uniform d / Λ shows better results. However other two structures also reports very low dispersion. Confinement loss obtained for all the three structures is of the order of 10
^-6
. All PCFs structure allow endlessly single mode propagation. In other words all structures investigated in this paper proves to be eligible candidate for optical communication system and high data transfer with very low loss.
