(a) Influence of Kerr effect and FCR on the spectral broadening. (b). Generation of free carriers in an optical pulse. Free carriers follow the integral of the optical pulse and accumulate toward the trailing edge of the pulse.
Influence of various physical phenomena on spectral broadening factor plotted as a function of the input intensity of the pulse.
Simulated optical spectra at an input intensity of showing free carrier induced effects.
(a) Spectral broadening factor as a function of the length of the waveguide, for three different input intensities. (b) Influence of TPA in reducing the optical intensity of the pulse for three different input intensities.
Experimentally observed continua for various input intensities.
Comparison of experimentally observed spectral broadening factor with simulated values, plotted as a function of the input optical intensity.
