An Effective Method for Prediction of the Field Distribution of Lp11 Mode of Dispersion Controlled Fibers Having Third Order Nonlinearity

Abstract

We present the first mode of higher order (LP11) modal field distributions of the dispersion-controlled fibers in the appearance as well as in omission of Kerr class nonlinearity. The research is totally based on a mathematical expression for the field of LP11 mode as prescribed by Chebyshev method. Mathematical solution for the relevant parameters is described. The method of iteration is used for the necessary prediction in existence of said class of nonlinearity. The concerned evaluation using the prescribed formulations requires little computations. But our results were shown to be extremely close to the actual values obtained by a methodology namely finite element. As a result, our simple and precise formalism provides ample scope for analyzing various Kerr class nonlinear dual-mode optical fiber properties.
