  • Cherif, Rim; Zghal, Mourad; Hamam, Habib (Institute of Electrical and Electronics Engineers Inc., 2007)
    We numerically analyze the stimulated Raman scattering (SRS) in nonlinear photonic crystal fibers (PCF). Generalized nonlinear Schrodinger equation was used to model the propagation of femtosecond pulses in PCF. We demonstrate ...
  • Dridi, Kais; Hamam, Habib (Institute of Electrical and Electronics Engineers Inc., 2007)
    In this study, we present an overview on recent existing methods to generate UWB signals. Given the increasing interest in the UWB over optical fiber, special attention will be devoted to optical methods for generating UWB ...
  • Dridi, Kais; Hamam, Habib (Institute of Electrical and Electronics Engineers Inc., 2007)
    We propose a novel approach for generating UWB signals for propagation over the optical fiber. This technique uses the effect of chromatic dispersion in single mode fibers, expressed by the Schrodinger equation. After ...
  • Dridi, Kais; Hamam, Habib (Institute of Electrical and Electronics Engineers Inc., 2007)
    We propose a new all optical fiber based Ultra-wideband (UWB) pulse generation for propagation over optical fibers (UWBoF). The approach is based on time delay. The technique consists in duplicating the input signal, ...
