Optimum design of a dispersion managed photonic crystal fiber for nonlinear optics applications in telecom systems

This paper presents an optimum design for highly nonlinear dispersion managed photonic crystal fibers. The APSS version 2.3 software is used as the simulation tool. According to simulation, an eight-ringed photonic crystal fiber can be designed with a high nonlinear coefficient at 1550 nm of the order 36.5 W

with simultaneously flatter dispersion characteristics and low confinement losses. This fiber also assumes a high birefringence and has a modest number of design parameters.
