Propagation Characteristics of Photonic Crystal Fiber: Scalar Effective Index Method & Fully Vectorial Effective Index Method

I. ABSTRACT The paper presents salient features of photonic crystal fiber (PCF) at one place. This paper focuses on the investigation of propagation characteristics of index guiding photonic crystal fibers from Scalar and Vectorial Effective index methods with an objective to compare and analyze the guided modes, spot size, spectral response of bend loss and spectral response of splice losses for various designs of PCF. Dispersion results so obtained from the above two methods is compared with the corresponding values of experimental result which points the range of validity and applicability of scalar and fully vectorial effective index methods for PCF. It is shown that the refractive index of fundamental space filling mode of PCF obtained by the above two methods matches well with that of finite element method (FEM) for the same design of PCF.
