Ultrashort soliton propagation in multi-clad optical fibers with per channel data rate of 1Tb/s

Propagation of ultrashort soliton has been investigated in multi-clad optical fibers namely multi-clad dispersion shifted fiber (MCDSF) and multi-clad dispersion flattening fiber (MCDFF) to achieve ultrahigh data rate of 1Tb/s. Third-order dispersion (TOD) as higher-order dispersive effect and intrapulse Raman scattering (IRS) and self-steepening (SS) as higher-order nonlinear effects has been considered in the study. Including all these effects propagation characteristics of fundamental soliton and higher-order soliton has been studied. Split-step Fourier (SSF) method has been used to solve nonlinear Schrodinger equation (NLSE) for observing the propagation characteristics. We also compared the propagation characteristics with other conventional fibers like nonzero dispersion shifted fiber (NZDSF), large effective area fiber (LEAF), standard single mode fiber (SSMF) and proposed MCDSF as the best suitable fiber for this massive data rate.
