Defect-Photonic Crystal Fiber structure of Zero Chromatic Dispersion and very low Confinement loss

Abstract

Photonic crystal fibers are being designed with promising results owing to design flexibility and structure geometry. A four-ring structure with ring defects has been proposed. The results show that Photonic crystal fiber with the third ring removed has very low confinement loss of 1.17x10-4dB/km at 1.55µm, chromatic dispersion of - 69ps/km.nm at 0.75µm and zero chromatic dispersion at 0.86µm. The results also show that removing only the third ring reduces chromatic dispersion at shorter wavelengths than at longer wavelengths. Vectorial Finite element method is used for this work. The proposed fiber can be used for short and medium transmission applications.
