Study the Effect of Some Photonic Crystal Arrangements on the Dispersion and Effective Refractive Index of Photonic Crystal Fiber

The recent optical fibers are the microstructure optical fibers (MOFs). They are consisting of a hexagonal arrangement of air holes along the length of a silica fiber surrounding a central core of solid silica. They can guide light through the total internal reection mechanism and photonic band gap eect. PCFs contain axially air channels which provide a large degree of freedom in design to achieve a variety of peculiar properties, numerous PCF-based sensors have been proposed, developed and demonstrated for a broad range of sensing applications, PCF is depends on different parameters such as the diameter of air hole, number of holes, and the distance between the air holes. This paper presents the results of the customizing of a photonic crystal ber. This customizing is essential to know the actual parameters of the PCF for its use in the application.
