A theoretical study of spectral properties of pulsed chirped Generalized beams in oceanic turbulence

Article scientifique 2023 Anglais

Résumé

Abstract Generalized Hermite cosh Gaussian (GHCG) beam has been produced as generalized beams with special profiles. The analytical expression of the intensity spectral of pulsed chirped GHCG beam passing through turbulent oceanic is derived using extended Huygens-Fresnel principle and the Fourier Transform method. The study examines various factors, including ocean turbulence, transverse position, and initial beam parameters, to understand their influence on the spectral intensity of the pulsed chirped GHCG beam by using numerical simulations. Moreover, the effects of both optical parameters and oceanic turbulence parameters on spectral shifts at different observation positions are discussed in detail. The results obtained provide a comprehensive understanding of the spectral transition of the pulsed chirped GHCG beam propagating through turbulent oceanic environments and hold potential applications in information coding and transmission for marine communication systems.
