“…They induce nonlinear coupling among overlapping optical pulses and thus lead to interchannel cross talk in conventional WDM SMF systems. In addition, FWM transfer energy from pumps to signal and newly generated idler waves adds additional noise and thus degrades the transmission system performance [22]. On the other hand, XPM in SMF can be applied in nonlinear pulse compression [23] and passive mode locking [24], while FWM can be used beneficially in SMF for wavelength conversion of WDM channels [25], as well as all-optical de-multiplexing [26].…”

In this work, nonlinear optical effects are exploited for future implementations of space-division multiplexing fiber systems. The paper first presents the fundamentals of intermodal nonlinear phenomena over few-mode fibers, such as cross-phase modulation, four-wave mixing (FWM), stimulated Brillouin scattering and stimulated Raman scattering. Second, the potential applications of fewmode nonlinear effects are discussed for sensing and optical signal processing. We demonstrated how fiber mode symmetries and linear mode coupling affect intermodal power transfer and spectral broadening. Lastly, the paper proposes a ultrafast all-optical simultaneous wavelength and mode conversion scheme based on intermodal FWM, with the capability of switching state of polarization and mode degeneracy orientation. Under this scheme, cross-polarization modulation and cross-mode modulation can be achieved.

“…This possibility was earlier experimentally demonstrated using a singlemode optical fibre with a standard mode area [6][7][8][9][10][11][12]. However, standard single-mode fibres with relatively small mode area exhibit correspondingly low non-linear effect threshold, not permitting pure linear dispersion compression even at average radiation powers as low as several tens of mW in picosecond pulses following at a megahertz repetition rate [13][14][15].…”

Linear compression of chirped pulses in optical fibre with large step-index mode area

The possibilities and limitations of linear compression of positively chirped pulses in the negative-dispersion region of a step-index large mode-area single-mode optical fibre are investigated for the first time. Analytical formulae for critical values of radiation power are found, below which pedestal-free pulse compression is possible down to the Fourier limit. It is demonstrated that at radiation powers exceeding these critical values, there exists an optimal compressing fibre length, over which laser pulses reach the minimum of the time-bandwidth product, and beyond which irreversible pulse deformation occurs. The modelling results agree well with the experimental data.

“…In optical physics, resonance and near-resonance interactions are usually modelled through either two-level amplification (TLA) or stimulated Raman scattering (SRS) process [7]. SRS process can be viewed as absorption of a photon from the pump pulse at frequency ω p and the emission of a photon at Stokes frequency ω s [8]. e difference in energy is taken up by molecular vibrations.…”

A theoretical and numerical investigation of transient dynamics of stimulated Raman scattering (SRS) inside gas-filled hollow-core photonic crystal fibers (HCPCFs) is reported here. A clear link between the transient dynamics and the coherent memory of the SRS interaction is demonstrated. In addition, the role of pulse width, pump power, fiber length, and gaseous medium in the transient dynamics of SRS in HCPCFs is discussed. It is shown that the coherent memory can serve as a convenient parameter to control the SRS propagation regime.
