TL;DR: The Peregrine soliton was observed experimentally for the first time by using femtosecond pulses in an optical fiber as mentioned in this paper, which gave some insight into freak waves that can appear out of nowhere before simply disappearing.
Abstract: The Peregrine soliton — a wave localized in both space and time — is now observed experimentally for the first time by using femtosecond pulses in an optical fibre. The results give some insight into freak waves that can appear out of nowhere before simply disappearing.

TL;DR: Light-by-light polarization control via a nonlinear effect occurring in single mode optical fibre is experimentally demonstrated, confirming yet another fascinating possibility to all-optical control the light properties in optical fibre.
Abstract: In many photonics applications, especially in optical fibre based systems, the state of polarization of light remains so far an elusive uncontrolled variable, which can dramatically affect the performances of that systems and which one would like to control as finely as possible. Here, we experimentally demonstrate light-by-light polarization control via a nonlinear effect occurring in single mode optical fibre. We observe a polarization attraction and stabilization of a 10 Gbit/s optical telecommunication signal around 1550 nm. We also validate the potentiality of the device to annihilate very fast nanosecond polarization bursts. This result confirms yet another fascinating possibility to all-optical control the light properties in optical fibre.

TL;DR: In this paper, the authors report progress on the design of all-fibered ultra-high repetition-rate pulse sources for telecommunication applications around 1550 nm, which are based on the nonlinear compression of an initial beat-signal through a multiple four-wave mixing process taking place into an optical fiber.

TL;DR: In this article, the emergence of rare and intense events in a Raman fiber amplifier is discussed, and approaches based on spectral slicing of the broadened spectra are proposed in order to isolate the rarest events.
Abstract: In this work, we discuss the emergence of rare and intense events in a Raman fiber amplifier. The temporal and spectral evolutions of continuous and pulsed signals are investigated, and approaches based on spectral slicing of the broadened spectra are proposed in order to isolate the rarest events. Numerical simulations are confirmed by experimental results.

TL;DR: Solli et al. as mentioned in this paper showed that a fiber-optical system can generate large amplitude extreme wave events with similar statistical properties to the infamous hydrodynamic rogue waves on the surface of the ocean, and discussed how this observation may open the possibility for an optical system to be used to directly study both the dynamics and statistics of extreme value processes, a potential advance comparable to the introduction of optical systems to study chaos in the 1970s.
Abstract: In this contribution we describe and discuss a series of challenges and questions relating to understanding extreme wave phenomena in optics. Many aspects of these questions are being studied in the framework of the MANUREVA project: a multidisciplinary consortium aiming to carry out mathematical, numerical and experimental studies in this field. The central motivation of this work is the 2007 results from optical physics [D. Solli et al., Nature 450, 1054 (2007)] that showed how a fibre-optical system can generate large amplitude extreme wave events with similar statistical properties to the infamous hydrodynamic rogue waves on the surface of the ocean. We review our recent work in this area, and discuss how this observation may open the possibility for an optical system to be used to directly study both the dynamics and statistics of extreme-value processes, a potential advance comparable to the introduction of optical systems to study chaos in the 1970s.

TL;DR: In this paper, the spectral dependence of the group modal birefringence in a nonlinear photonic crystal fiber has been studied both numerically and experimentally, and the sign inversion and cancellation of group modality in the telecommunication window is demonstrated.
Abstract: The spectral dependence of the group modal birefringence in a highly birefringent nonlinear photonic crystal fibre is studied both numerically and experimentally. The sign inversion and the cancellation of the group modal birefringence in the telecommunication window is demonstrated. Two simple experimental techniques are used to evaluate the wavelength of zero polarisation mode dispersion. The experimental results are in excellent agreement with numerical calculations based on vectorial beam propagation method simulations.

TL;DR: In this article, a spectral-phase-coded OCDMA using a fiber-based saturable absorber as thresholding in the receiver is presented, where the spectral phase coding is applied to the short pulses.
Abstract: Intended for the next generation of optical access networks, OCDMA is of great interest to meet the demand of increasing the number of users per access fiber, especially as spectral phase coding increases its performance in the optical domain. This, however, requires handling broad spectra and short pulses, which are best dealt with using opto-electronic or all-optical devices instead of slower electronics. Among others, we demonstrate spectral-phase-coded OCDMA using a fiber-based saturable absorber as thresholding in the receiver.

TL;DR: In this article, the experimental achievement of all-fibered polarization attraction, which can occur in optical fibers at telecommunication wavelengths, was reported for the first time, and it was shown that it is possible to all-optically control and stabilize the state of polarization of a 10 Gbit/s telecommunication signal through the injection of a counter-propagating control pump wave.
Abstract: In this work, we report for the first time the experimental achievement of an all-fibered polarization attraction, which can occur in optical fibers at telecommunication wavelengths. More precisely, we have experimentally shown that is possible to all-optically control and stabilize the state of polarization of a 10 Gbit/s telecommunication signal through the injection of a counter-propagating control pump wave. Eye diagrams recordings and bit error rate measurements have shown that this new type of all-optical function, almost lossless and instantaneous has a promising potential for telecommunication applications.

TL;DR: In this paper, a review of the recent work in the field of optical rogue wave physics and applications is presented, with a brief survey of the well-known noise and incoherence processes in optical fiber supercontinuum generation, and links to recent developments in studying the emergence of high contrast localised breather structures in both spontaneous and induced nonlinear instabilities.
Abstract: We review our recent work in the field of optical rogue wave physics and applications. Beginning from a brief survey of the well-known noise and incoherence processes in optical fiber supercontinuum generation, we trace the links to recent developments in studying the emergence of high contrast localised breather structures in both spontaneous and induced nonlinear instabilities. In the latter case, we discuss our recent measurements that have reported the experimental observation of the Peregrine soliton, a unique class of rational soliton predicted to exist over 25 years ago and never previously observed.
