Phenomenological model for spectral broadening of incoherent light in fibers via self-phase modulation and dispersion

Abstract: A phenomenological model for spectral broadening of incoherent light in silica fibers via self-phase modulation and dispersion is presented, aiming at providing a qualitative and readily accessible description of incoherent light spectral broadening. In this model, the incoherent light is approximated by a cosine power-modulated light with modulation parameters depending on the coherent time and the dispersion in fibers. A simple and practical method for spectral broadening predictions is given, and demonstrat… Show more

“…Note that the inherent to SPM ASE spectral broadening in optical fiber and its dispersion were recently modeled [19] in assumption that ASE as pump for SCG is harmonically modulated signal with some average frequency and magnitude. The found above laws may shed more light on the physics behind the phenomenon.…”

“…We first simulate a STOV with partial temporal coherence. To simulate partial coherence, we apply a random phase on each temporal frequency of a coherent wave packet [8,9] . The probability of the phase follows a normal random distribution where we control the amount of randomness with the standard deviation, σ ω .…”

“…The gain effect is generally made up of gain narrowing [4,5] and gain saturation [6,7], which have great influence on pulse characteristics. Many studies about nonlinear effects have been published [8][9][10]. Herein, we investigate the influence of gain effects on the pulse evolution in fiber amplifiers.…”
