Abstract:

A new class of Honey Comb Photonic Crystal Fibres (PCFs) structure that has a high-index core surrounded by air holes is proposed. For the proposed design four different air-hole diameters surrounding core region is used. A full vector Finite Difference Time Domain (FDTD) analysis with  the Transparent Boundary conditions (TBC) absorbing boundary conditions  is effectively applied to investigate the model characteristics of Photonic Crystal Fibres (PCFs) Through the numerical simulation and optimizing the geometrical parameters like changing the pitch (Λ) for photonic crystal fibers in Honey Comb structure, it has been demonstrated that it is possible to obtain ultra flatten dispersion over a wide wavelength range. The designed index-guiding Honey Comb PCFs has a nearly zero ultra-flattened dispersion of O±O.11ps/(nm.km) in a wavelength range of 1.4 µm to 1.6µm. The proposed structure is designed using seven rings in which circular air holes are used. The background material for the designing purpose is silica with refractive index 1.458.  Moreover, a detailed study of PCF with honeycomb lattice has been carried out with the purpose of optimizing the chromatic dispersion.
