Review and theory of optical soliton generation used to improve the security and high capacity of MRR and NRR passive systems

Abstract

We review the generation, application and theory of soliton pulses in a nonlinear fiber optic medium to improve the security and capacity of optical passive systems such as add/drop and PANDA ring resonators. The improvement of the ring resonator passive systems depends on the output signals, where the chaotic signal generation within the systems is the critical properties of the output signals which can be used to enhance the security and capacity. The passive ring resonator systems are constructed by a nonlinear Kerr effect fiber optic to produce optical signals in the form of chaotic and multi dark and bright soliton pulses applied in many areas of engineering, biotechnology and communications. In this research, we review the generation and applications of soliton signals and theory of the main ring resonator passive systems as add/drop and PANDA ring resonators, where the easy controlling of the output signals is the benefit of using these systems due to the interferometric roles.
