Appropriate Choice of Lorentzian Approximation of the Fundamental mode from different versions to study Propagation Characteristics of Single Mode Fiber

Abstract

In this paper, we approximate the fundamental mode of guided propagation in three Lorentzian approximations (LZ0, LZ1, LZ2) sequentially with an expectation of improvements in the performance of propagation characteristics for single mode step index linear optical fiber within scalar variational framework. We show that the improvements in the performance of propagation characterics, normalized propagation constant- ( b(V ) ), group delay- ( d(V ) ) and especially wave guide dispersion ( g(V ) ) version wise in the graphical presentation.
