The nonlinear Schrödinger equation (NLSE) is a central model of science, applying to hydrodynamics, plasma physics, molecular biology and optics. NLSE admits only few elementary analytic solutions, but one in particular describing localized soliton on finite background intense current interest the context understanding physics extreme waves. However, although first solution this type was Kuznetzov-Ma (KM) derived 1977, there have fact been no quantitative experiments confirming its validity....
Numerical simulations of the onset phase continuous wave supercontinuum generation from modulation instability show that structure field as it develops can be interpreted in terms properties Akhmediev Breathers.Numerical and analytical results are compared with experimental measurements spectral broadening photonic crystal fiber using nanosecond pulses.
The pioneering paper 'Optical rogue waves' by Solli et al (2007 Nature 450 1054) started the new subfield in optics. This work launched a great deal of activity on this novel subject. As result, initial concept has expanded and been enriched ideas. Various approaches have suggested since then. A fresh look at older results discoveries undertaken, stimulated 'optical waves'. Presently, there may not unique view how scientific term should be used developed. There is nothing surprising when...
We report theoretical, numerical, and experimental studies of higher-order modulation instability in the focusing nonlinear Schr\"odinger equation. This arises from superposition elementary instabilities, associated with initial single breather evolution followed by a regime complex, yet deterministic, pulse splitting. analytically describe process using Darboux transformation compare experiments optical fiber. show how suitably low frequency on continuous wave field induces splitting...

We report the fabrication and characterization of first guiding chalcogenide As(2)S(3) microstructured optical fibers (MOFs) with a suspended core. At 1.55 microm, measured losses are approximately 0.7 dB/m or 0.35 according to MOF core size. The have been designed present zero dispersion wavelength (ZDW) around 2 microm.

Water, plasmas, and laser light can all exhibit instabilities. Experiments in two different areas of wave physics are used to investigate the creation annihilation dynamics superregular breather waves, which combine form an instability.
Recently nonlinear fiber optics has revealed the existence of ``breathers,'' a new form solitons with periodic oscillations on finite background. But, how do such breathers, when they appear at same time, interact each other? A experiment demonstrates that two their initial shapes and propagations are properly controlled, can collide to make giant ``rogue'' wave.
Abstract Instabilities are common phenomena frequently observed in nature, sometimes leading to unexpected catastrophes and disasters seemingly normal conditions. One prominent form of instability a distributed system is its response harmonic modulation. Such has special names various branches physics generally known as modulation (MI). The MI leads growth-decay cycle unstable waves therefore related Fermi-Pasta-Ulam (FPU) recurrence since breather solutions the nonlinear Schrödinger...
We present experimental and numerical results showing the generation breakup of Peregrine soliton in standard telecommunications fiber. The impact nonideal initial conditions is studied through direct cutback measurements longitudinal evolution emerging dynamics shown to be associated with splitting into two subpulses, each subpulse itself exhibiting characteristics. Experimental are good agreement simulations.
Abstract Photonics enables to develop simple lab experiments that mimic water rogue wave generation phenomena, as well relativistic gravitational effects such event horizons, lensing and Hawking radiation. The basis for analog gravity is light propagation through an effective moving medium obtained via the nonlinear response of material. So far, analogue kinematics was reproduced in scalar optical test models. Multimode spatiotemporal interactions exhibit a rich spectrum excitations, which...
We present both a theoretical description and experimental observation of the nonlinear mutual interactions between pair copropagative breathers in framework focusing one-dimensional Schrödinger equation. As general case, we show that resulting bound state exhibits moleculelike behavior with quasiperiodic oscillatory dynamics (i.e., internal coherent pulsations), while for commensurate conditions molecule oscillations become exactly periodic. Our model is confirmed by an shaped breather...
Over the past decade, rogue wave debate has stimulated comparison of predictions and observations among different branches physics, particularly between hydrodynamics optics, in situations where analogous dynamical behaviors can be identified, thanks to use common universal models. Although scalar nonlinear Schroedinger equation (NLSE) constantly played a central role for investigations, moving beyond standard NLSE model is relevant needful describing more general classes physical systems...
We describe generalized nonlinear envelope equation modeling of sub-cycle dynamics on the underlying electric field carrier during one-dimensional propagation in fused silica. Generalized simulations are shown to be excellent quantitative agreement with numerical integration Maxwell's equations, even presence shock and steepening a sub-50 attosecond timescale. In addition, by separating effects self-phase modulation third harmonic generation, we examine relative contribution these...
The Akhmediev breather formalism of modulation instability is extended to describe the spectral dynamics induced multiple sideband generation from a modulated continuous wave field. Exact theoretical results describing frequency domain evolution are compared with experiments performed using single mode fiber around 1550 nm. theory shown reproduce depletion an injected pump and Fermi–Pasta–Ulam recurrence recovery towards initial state. Realistic simulations including higher-order dispersion,...
In this work, we report the experimental observation of supercontinua generation in two kinds suspended-core microstructured soft-glass optical fibers. Low loss, highly nonlinear, tellurite and As2S3 chalcogenide fibers have been fabricated pumped close to their zero-dispersion wavelength femtosecond regime by means an parametric oscillator a Ti:Sapphire laser. When coupled into fibers, pulses result 2000-nm bandwidth reaching Mid-Infrared region extending from 750 nm 2.8 µm 1 3.2 respectively.
Parabolic pulses in optical fibers have stimulated an increasing number of applications. We review here the physics underlying generation such as well results obtained a wide range experimental configurations.
We show the emergence of rogue wave events from optical turbulence by analyzing long term evolution field. In particular, we identify three turbulent regimes depending on incoherence in system.
An As2S3 fiber-based supercontinuum source that covers 3500 nm, extending from near visible to the midinfrared, is successfully reported by using a 200-fs-pulsed pump with nJ-level energy at 2.5 μm. The main features of our are two-fold. On one hand, low-loss microstructured optical fiber has been fabricated, typical attenuation below 2 dB/m in 1–4 μm wavelength range. other 20-mm-long sample sufficient enable spectral broadening, spreading 0.6 4.1 40 dB dynamic
We report the first experimental observation of periodic breathers in water waves. One them is Kuznetsov-Ma soliton and another one Akhmediev breather. Each a localized solution nonlinear Schrödinger equation (NLS) on constant background. The difference localization which either time or space. experiments conducted wave flume show results that are good agreement with NLS theory. Basic features include maximal amplitudes spectra consistent theoretical predictions.
We demonstrate far-detuned parametric frequency conversion processes in a few mode graded-index optical fibers pumped by Q-switched picosecond laser at 1064 nm. Through detailed analytical and numerical analysis, we show that the multiple sidebands are generated through complex cascaded process involving inter-modal four-wave mixing. The resulting wavelength detuning spans visible down to 405 nm near-infrared up 1355
