Study and modeling of photonic crystal fibers

"Optical fiber is a light guide which today constitutes the preferred medium for the transport of information. But, in order to meet the increasing needs generated by the development of the Internet in particular, it was necessary to always improve the propagation characteristics in the fibers. A new generation of fibers has been designed with the aim of obtaining lower losses and better performance than classical fibers. This work presents a design of hexagonal photonic crystal fiber (PCF) geometry for analyzing different optical properties with respect to wavelength ranging. This geometry has been used for analyzing effective refractive index, dispersion, effective mode area, nonlinear coefficient and birefringence. Silica glass is chosen as background material and the cladding region is made of air hole layers. This work is based on the modeling and analysis of the propagation characteristics of waves in a photonic crystal fiber."
