We have proposed novel designs of different three Structures Honeycomb Photonic Crystal Fiber (HPCF) with silica core material, Large core Hexagonal Photonic Crystal Fibers with Chalcogenide As2Se3 glass Core Material and Hexagonal Photonic Crystal Fibers with Borosilicate crown glass (BK7) Core Material. The study is carried out on dispersion characteristic of PCF. In this book, We have proposed a novel structure of different three Photonic Crystal Fiber and investigation is carried out on the refractive index distribution of air hole rings in a Photonic band gap fiber as a function of the pitch. The pitch is defined as the distance between two holes in the lattice structure of Photonic Crystal Fiber.
Here, We have considered an air-silica honeycomb lattice, large core hexagonal lattice and demonstrate a new approach to the formation of a core defect. The honeycomb lattice has recently been suggested for the formation of a photonic band-gap guiding...
