Simple Determination of Splice Loss in Single Mode Graded Index Fibers Using Gaussian Spot Size of Marcuse Formulation

Abstract

A simple technique is presented to determine splice losses between two identical arbitrarily graded index single mode fibers for transverse and angular misalignments. The power transmission coefficients at the splice are calculated in terms of spot size using Marcuse formulation for graded index fibers. Our values of splice losses match excellently with the exact one and also other results available in literature. The technique should attract attention of experimentalist as a simple alternative of rigorous methods to estimate propagation characteristics
