WebFeb 12, 2024 · Abstract. In this paper, the existence and stability of the nonlinear spatial localized modes have been investigated for both self-focusing and self-defocusing in the nonlinear Schrödinger (NLS) equation with interplay of third-order dispersion (TOD), momentum term and complex parity-time \((\mathcal {PT})\)-symmetric Scarf … WebThird-order dispersion of glass. When working with short laser pulses, it is important to compensate the dispersion of a pulse passing through a material because it changes the …
