Simple approach to find out fiber parameters and characteristics using Marcuse spot sizes applied to Variational Formalism

Abstract

In this paper, we report for the first time to the best of our knowledge that for a given value of fiber spot size, obtained from Marcuse’s relation, one can accurately and easily determine the fiber parameters for a particular normalized frequency using Variational formalism. Then we have shown that with a typical example of fractional power in the core, this technique can also accurately predict propagation characteristics
