Study and Synthesis of the Propagation of Ultrashort Laser Pulses in Medias: Fused Silica, Photonic Crystal Fiber, Air Silica and Hollow Core

Abstract

Abstract Ultrashort lasers pulses have a pulse width in the pico or femtosecond range. Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide have received a great deal of attention in the recent years. Our goal in this paper is to study the propagation characteristics of that pulse in a nonlinear medium. In analyzing these characteristics, the nonlinear effects along with the dispersion are taking into account. Additionally, the considered nonlinear effects include self phase modulation (SPM), sel steepening (SS), cross phase modulation (XPM) and stimulated Raman scattering (SRS).
