A Comprehensive Study on Phase Sensitive Amplification and Stimulated Brillouin Scattering in Nonlinear Fibers with Longitudinally Varying Dispersion

“…We also note by comparing the top and bottom rows of Figures 9 and 10, that for a low nonlinearity, i.e., when the nonlinear phase is 0.6 rads, the analytical 3-wave model agree satisfactorily with the numerical NLSE model. However, when the nonlinear phase is 1.5 rads, the analytical model predicts a much larger gain than the numerical one for β 2 = −5 ps 2 /km and β 2 = 5 ps 2 /km [43,46]. For β 2 = 0 ps 2 /km, not only the analytical model overestimates the maximum gain, it also predicts a shorter gain ripple wavelength.…”

“…In this section we focus on a single pump configuration. Single pump configurations are often simpler in terms of theoretical treatment since they do not contain high-order pumps that are generated through cascaded four-wave mixing between the pumps in a dual pump configuration [42,43].…”

“…which is the parametric gain coefficient for a standard HNLF in a dual-pump configuration with a degenerate signal [43].…”

Predicting nonlinear reshaping of periodic signals in optical fibre with a neural network

“…Nevertheless, the validity of the truncated model is limited by the emergence of higher-order spectral sidebands that typically occurs in practice due to further wave mixings. Semi-analytical models involving a higher number of frequency components have been explored [15][16][17], but their complexity and underlying assumptions may restrict their practical implementation. In this paper, we implement an artificial NN to predict the spectro-temporal evolution of a periodic waveform signal upon its nonlinear propagation in an optical fibre.…”

Characteristics of Nonstatic Quantum Light Waves: The Principle for Wave Expansion and Collapse

“…In order to interpret quantum mechanics based on particle-wave duality and non-locality, it is necessary to know the fundamental relation between quantum wave phase and the associated physical reality [5]. For decades, considerable research has been devoted to phase sensitive experiments with the waves that undergo intraatomic/intramolecular propagation [6][7][8][9], as well as free wave-packets. The development of techniques for controlling and manipulating quantum phases may open a new route for a variety of their applications, for example, in wireless communications [10,11], tunable optical devices [12], beam forming and scanning [13,14], radar detection [15], and biological monitoring [16,17].…”
