Energy Exchange Between the Polarization Components of an Optical Pulse Under the Influence of Degenerate Four-Photon Parametric Processes

Abstract

The present paper investigates the process of energy exchange between the components of an optical pulse that is propagating in a nonlinear dispersive medium under the influence of degenerate four-photon parametric processes. The effects of self-phase modulation (SPM) and cross-phase modulation (XPM) have been taken into account. The obtained results demonstrate that no energy exchange takes place between the optical components of the pulse when the initial polarization is linear or circular. In the presence of initial elliptical polarization, energy exchange can be observed. The intensity of the energy transmission and its period can be determined using the values of the initial energies and the initial phase difference between the optical components of the pulse.
