Quiescent Optical Solitons for the Concatenation Model with Nonlinear Chromatic Dispersion

This paper recovers quiescent optical solitons that are self-sustaining, localized wave packets maintain their shape and amplitude over long distances due to a balance between nonlinearity dispersion. When soliton is in state of quiescence, it means stationary both space time. Quiescent typically observed fibers, where dispersion can lead the formation solitons. The concatenation model considered understand behavior pulses propagating through nonlinear media. Here, we consider familiar Schrödinger equation, Lakshmanan–Porsezian–Daniel Sasa–Satsuma equation. current also addresses with chromatic dispersion, phenomenon occurs fibers other dispersive media, material modified by effects. In presence nonlinearities, such as self-phase modulation cross-phase modulation, coefficient becomes function intensity, resulting A full spectrum solitons, along straddled obtained. There four integration schemes made this retrieval possible. numerical simulations included for these parameter constraints indicate existence criteria
