Abstract
With the rising requirement for high capacity, low latency and energy-efficient optical communication, the need for strict mathematical models of the nonlinear dynamics of photonic systems has grown. In this study, a mathematical framework based on the Hamiltonian formalism is developed for the characterization of the nonlinear dynamics in advanced optical communication systems. The proposed formulation is the result of a natural evolution of optical amplitude, phase, dispersion, nonlinear interaction and energy exchange expressed in coupled Hamiltonian state equations. A Hamiltonian functional is derived for a generalized description of the conservative and nonlinear parts of the propagation of photons, and perturbation terms are added to describe the effect of attenuation, noise, and external disturbances. The resulting model allows the analytical study of system stability, conservation of quantities, nonlinear energy transfer, phase evolution and propagation dynamics. A second method is the use of Hamiltonian phase space analysis to determine stable and unstable operating regions and to measure the impact of the nonlinear coefficients, dispersion parameters and channel perturbations on the communication performance. Mathematical simulation using numbers is performed to show the ability of the proposed mathematical structure to predict nonlinear distortion and to show a physically interpretable representation of the evolution of the optical signals, with the prediction of nonlinear distortion and dynamical transitions. The model provides a non-linear framework for studying nonlinear photonic systems and could be used to support theoretical design and optimization of advanced optical communication links.
