“…More recent studies have also investigated the interaction of an intense pulse with its own dispersive wave (DW) [15] or the trapping of a DW between two solitons [16,17]. Interactions involving higher order solitons [18] or dark solitons [19] have also been considered. Owing to the essential role played by the dispersion properties of the structure for the observation of an optical event horizon, almost all these demonstrations have been performed in photonic crystal fibers (PCF's), for which quasi on-demand dispersion properties can be engineered.…”

The scattering of a linear wave on an optical event horizon, induced by a cross polarized soliton, is experimentally and numerically investigated in integrated structures. The experiments are performed in a dispersion-engineered birefringent silicon nanophotonic waveguide. In stark contrast with co-polarized waves, the large difference between the group velocity of the two cross-polarized waves enables a frequency conversion almost independent on the soliton wavelength. It is shown that the generated idler is only shifted by 10 nm around 1550 nm over a pump tuning range of 350 nm. Simulations using two coupled full vectorial nonlinear Schrödinger equations fully support the experimental results.Nonlinear interactions between linear waves and solitons attract a tremendous amount of interest in the scientific community for many years. In this framework, interactions between waves of similar group velocities particularly draw the attention of researchers for their potential useful applications such as frequency converters [1] or for future optical transistor-like devices [2]. In this particular process, the propagation of an intense solitonic pump in a Kerr medium induces a moving refractive index perturbation which in turn leads to a frequency conversion of a weak probe wave through a cross-phase modulation (XPM) process. In the context of supercontinuum (SC) generation, this process helps understanding the underlying physics of the spectral broadening [3], and has also been demonstrated to enable the generation of highly coherent broadband SC [4,5] in a complementary manner from the well-known process involving the soliton fission [6][7][8]. Recently, this nonlinear interaction has been reinterpreted as the optical analog of the event horizon of black and white holes [9,10]. As the propagation takes place in a dispersive media, the frequency conversion of the probe wave is accompanied by a modification of its group velocity, which is either accelerated or decelerated preventing any crossing between the two waves. The intense pulse thus constitutes an horizon that light can neither join nor escape. These so-called optical event horizons have thus also been largely studied for their analogy with general relativity and in particular with the Hawking radiation [9].Since its first theoretical prediction made by Yulin et al. a decades ago [11,12], and its experimental observation in the context of SC generation in optical fibers [13], numerous experimental demonstrations have been realized. We can cite studies involving the superimposition of a linear wave to an intense pump at the waveguide input [9,10,14], or the interaction between two pulses [1]. More recent studies have also investigated the interaction of an intense pulse with its own dispersive wave (DW) [15] or the trapping of a DW between two solitons [16,17]. Interactions involving higher order solitons [18] or dark solitons [19] have also been considered.

“…[1][2][3][4][5][6][7][8] In general, a temporal interface is the boundary in time separating two regions of different refractive indices; [3] such an interface can be produced using a co/counterpropagating pulse via cross-phase modulation. [9][10][11] As the optical pulse crosses the boundary, it splits into two parts with different spectra that behave like reflected and transmitted pulses. [12] They are temporal analogues of reflection and refraction of light in the space domain.…”

Reflection and Refraction of an Airy Pulse at a Moving Temporal Boundary

et al. 2020

View full text Add to dashboard Cite

Reflection and refraction of Airy pulses at a moving step refractive-index boundary are investigated. A comb-like reflected spectrum and an Airy-like transmitted spectrum are formed as an Airy pulse crosses a temporal boundary without initial group velocity mismatch or initial central frequency shift. The reflected and refracted pulses are significantly influenced by the location of temporal boundary and time-dependent refractive index change. The energy of each lobe of the comb-like reflected spectra can be controlled by changing the value of decay factor of the Airy pulse. In the case of an Airy pulse with an initial launch frequency shift, the reflected and refracted frequency shifts depend on the dispersion relation of the medium. The results can be used in potential applications involving optical manipulation.

“…The interaction of bright solitons with linear waves has also been studied in the case of high-order solitons [13], orthogonally polarized solitons [14], or in cavities made by solitons in which multiple collisions can be observed [5,[15][16][17]. The collision of linear waves with dark solitons has been also investigated theoretically and numerically in [18].…”

We report an experimental observation of the collision between a linear wave propagating in the anomalous dispersion region of an optical fiber and a dark soliton located in the normal dispersion region. This interaction results in the emission of a new frequency component whose wavelength can be predicted using phase-matching arguments. The measured efficiency of this process shows a strong dependency with the soliton grayness and the linear wave wavelength, and is in a good agreement with theory and numerical simulations.
