Comparative Study for Confinement loss using Different Geometrical Configuration of Photonic Crystal Fiber

This thesis submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Electronics and Telecommunication Engineering of East West University, Dhaka, BangladeshIn this thesis we deal with the Photonic crystal fiber. Here photonic crystal fiber was designed with different geometrical structures and shape. From these structures confinement losses were calculated using finite element method. Photonic Crystal Fibers were designed with various air hole rings with perfectly matched absorbing layer. COMSOL Multiphysics simulation software was used to design these structure and obtaining results. The value of pitch which means the distance between two air holes and the value of diameter of a particular hole were varied. From the simulated results, least confinement loss for a particular structure was suggested
