Abstract: | The all-optical communication system plays an important role in the recent information technology, in which the study and analysis of optical solitons will be the most intensive domain in optics. In this thesis work, the propagation of optical soliton in a real fiber system has been analysed from various methods. In optical fibers, solitons can rotate by selecting a correct signal and fiber properties, to achieve a balance between Group Velocity Dispersion (GVD) and Self-Phase Modulation (SPM). This research thesis describes the knowledge about optical solitons in different inhomogeneous fibers with inhomogeneous cause to introduce the optical fiber communication system. The solitons have been theoretically demonstrated and experimentally observed in optical fibers, thus the optical solitons will be interesting field in the optical communication systems. The propagation of the picosecond optical solitons in a monomode fiber is governed by the nonlinear Schrödinger (NLS) equation. In this thesis work, optical soliton propagation in various dispersion decreasing fibers (DDF) for different modulated profiles and nonlinear tunneling of soliton in a monomode fiber system are investigated. Besides, Darboux transformation techniques have been used to study the soliton dynamics to reveal the feature of the considered system to improve the soliton-based communication system. Darboux transformation method is used depend on the Lax couple of NLS formula. On the other hand, to discuss the feature of solution, soliton solutions are plotted by employing software tool. newlineIn the optical fiber media, always there are inhomogeneities which influence on gain or loss, group velocity dispersion (GVD) and self-phase modulation (SPM). Compared to the NLS type equations with constant modulated coefficients, the generalized ones with variable coefficients are more efficient in describing those physical problems newline |
