CHIRPED COSH–GAUSSIAN OPTICAL PULSES WITH KUDRYASHOV’S FORM OF SELF-PHASE MODULATION BY VARIATIONAL PRINCIPLE

This research work brings forth the understanding of optical cosh-Gaussian dynamics by incorporating the newly formulated Kudryashov equation. The method used is Anderson’s variational approach. We show that an appropriate choice of the trial wavefunction allows highlighting several varieties of stable and unstable solutions corresponding to non-dissipative or dissipative spatiotemporal solitons, propagating without deformation and with deformation.
