Analysis of loss mechanisms in photonic crystal fibers

Abstract

Analysis of different loss mechanisms that occurs in photonic crystal fibers (pcfs) is discussed. It is shown that loss appears when these fibers are either joined with another fiber or bent in a radius. The joint losses are obtained for transverse as well as angular misalignments. Peterman spot size definitions are used to define these losses. Bending losses in pcfs are also obtained for different designs of pcfs. It is observed that these loss definitions show dependence on the photonic crystal cladding parameters.
