A number of third order nonlinear processes can occur in single-mode fibres and an 8 understanding of such phenomena is almost a prerequisite for actual lightwave-system designers. 9 In this paper we review the main limitations imposed by several nonlinear effects, namely the self10 and cross-phase modulation, four-wave mixing, stimulated Raman scattering and stimulated 11 Brillouin scattering,...

In this paper, all-optical short-time Fourier transform (STFT) based on stimulated Brillouin scattering (SBS) is proposed and further used for real-time time-frequency analysis of different radio frequency (RF) signals. the STFT scheme, SBS not only provides a band-pass filter implementing window function in conjunction with periodic frequency-sweep optical signal but also obtains domain inform...

Repeater spacing in fiber optic communication is optimized taking into consideration various parameters such as fiber attenuation, Stimulated Brillouin Scattering (SBS), Stimulated Raman Scattering (SRS), fiber attenuation, photodiode sensitivity and input power. In our work, we have taken a trade off between power threshold in order to reduce SBS varying the effective fiber length and effectiv...
