Realizing the effect of soliton interaction with third order dispersion (TOD) in 100 Gbps telecommunication system

Abstract

In this work, we study the effect of in-phase soliton interaction with and without the effect of third order dispersion (TOD) in 100Gbps telecommunication system. The relative spacing of soliton is chosen as 5.28 (qo) and their interaction is noted in one collision period or length (Lcoll). The soliton interaction without TOD is noted with 2=-2.55ps2/Km and with TOD near Zero Dispersion (ZD) point of -0.22ps2/Km. The effect of TOD decreases the interaction effect when noted with TOD value of 3=0.01 ps3/Km and further there was no interaction with high value of 3=0.1 ps3/Km. The main characteristic of TOD causing temporal shifts is noted in in-phase solitons where thehigher deviation is noted with 3=0.1 ps3/Km than 3=0.01 ps3/Km. Further, we have also examined the effect of TOD with 3 and 6 solitons pulses to note the interaction effect. Finally it could be seen that when more than 2 soliton pulses are launched, TOD would degrade the system performance, where these adjacent pulses cross each other due to temporal shifts.

Generation and transmission of fractional‐order optical bright solitons in single mode fiber

“…In nonlinear dispersive fiber, the 2OD dispersive span and nonlinear span (NL s ) are almost equalized ( D s ≈ NL s ), together with 2OD dispersive span, which is less than 3OD dispersive span ( D s ≪ D s ′ ). The full width at half maximum ( T FWHM ) is linked with initial pulse width; its relation is given below, where T i is initial pulse width of fractional‐order OBS and T FWHM is the pulse full width at half maximum time. The given relation assists in the creation of fractional‐order OBSs envelope.…”

“… where S D is dispersion slope, β 3 and β 2 are 3OD and 2OD and c is the speed of light. The nonlinear span is manifested below, where P pi is peak power of fractional‐order OBSs envelope, the below equation supports the computation of initial peak power …”

“…The propagation of optical solitons through optical fiber is an extensive area of research with its valuable performance in all optical communication framework. The nonlinear Schrodinger equation (NLSE) is vastly utilized to display models in several areas such as nonlinear optics, optoelectronics, nonlinear sciences, mathematical biosciences, plasma physics, theoretical physics, nuclear physics, physical science and many more . The features of NLSE are contributed in text books on nonlinear optics .…”
