A simple but accurate technique for study of single-mode Kerr type nonlinear dispersion-shifted and dispersion-flattened fibers

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

“…4 and 5 illustrates the changes of the LP11 field ψ(R) with R for the above mentioned two graded W fibers. Likewise, we continue our analysis on two standard fibers having step W profile with the same V number 2.0 and C value 2.0 but differing ρ values as 1.3333 and 1.2500 (Ray et al, 2020;Monerie, 1982). Proceeding as before, we predict the LP11 field of these two standard fibers having step W profile for the chosen types of nonlinearity and in omission of nonlinearity.…”

“…For fibers with S=0.25, 0.50 and 0.75, the change of LP11 mode field ψ(R) with normalized radius path (R) is shown in Figures 1, 2, and 3. We take two parabolic kind W fibers with the same V value 3.0 and C value 1.5 but differing in ρ values, 1.4975 and 1.5000 (Ray et al, 2020;Mishra et al, 1984). Next, following the procedure as mentioned in the case of trapezoidal fibers, the field of LP11mode for these two categories of graded W fibers are assessed.…”

“…The literature also includes predictions of the LP11 modal field for GIF using the same formalism in the appearance and omission of Kerr nonlinearity. The accuracy of Chebyshev formalism to the analysis of mono-mode Kerr category nonlinear DSF and DFF has been added recently to the literature (Ray et al, 2020).…”
