Impact of amplitude jitter and signal-to-noise ratio on the nonlinear spectral compression in optical fibres

Abstract

Abstract:We numerically study the effects of amplitude fluctuations and signal-to-noise ratio degradation of the seed pulses on the spectral compression process arising from nonlinear propagation in an optical fibre. The unveiled quite good stability of the process against these pulse degradation factors is assessed in the context of optical regeneration of intensity-modulated signals, by combining nonlinear spectral compression with centered bandpass optical filtering.The results show that the proposed nonlinear processing scheme indeed achieves mitigation of the signal's amplitude noise. However, in the presence of a jitter of the temporal duration of the pulses, the performance of the device deteriorates.

Impact of initial pulse characteristics on the mitigation of self-phase modulation by sinusoidally time varying phase

“…We also expect that some features of the spectral compression process driven by SPM discussed in our previous work (Boscolo et al 2017b) can be readily extended to the SPM-mitigation scheme described in this paper so that the present scheme should be rather stable against amplitude fluctuations and signal-to-noise ratio degradation of the input pulses. We also believe that, similarly to a nonlinear spectral compression stage, the present technique could be combined with fiber laser architectures into new cavity designs (Ilday,Wise 2002;Boscolo et 22 al.…”

Offsetting Self-Phase Modulation in Optical Fibre by Sinusoidally Time-Varying Phase

“…We believe that the present study can provide a deeper insight into the association of the SPM effects with an external sinusoidal phase modulation and can be of interest for multistage fibre amplifier architectures. We also expect that some features of the spectral compression process driven by SPM discussed in our previous work [15] can be readily extended to the SPM-mitigation scheme described in this paper so that the present scheme should be rather stable against amplitude fluctuations and signal-to-noise ratio degradation of the input pulses. We also believe that, similarly to a nonlinear spectral compression stage, the present technique could be combined with fibre laser architectures into new cavity designs [16,17].…”
