Turbulent Dynamics of an Incoherently Pumped Passive Optical Fibre Cavity: quasi-solitons and dispersive waves

HAL (Le Centre pour la Communication Scientifique Directe) (2014)

Matteo Conforti Arnaud Mussot Julien Fatome Stéphane Pitois Kamal Hammani

We study numerically and experimentally the dynamics of an incoherently pumped passive optical fibre ring cavity. We show that the cavity exhibits a quasi-soliton turbulence dynamics, whose properties are controlled by the degree of coherence of the injected pump wave: as the coherence of the pump is degraded, the cavity exhibits a transition from the quasi-soliton turbulent regime toward the weakly nonlinear turbulent regime characterized by short-lived rogue wave events. This behavior is reminiscent of the corresponding dynamics obtained in the purely conservative (Hamiltonian) problem. Experimental results are reported by using a standard telecommunication optical fibre system.

Inline Photothermal Surface Plasmon Detector Integrated in Titanium Dioxide Waveguides

IEEE Journal of Quantum Electronics (2023)

Andrés Martinez Vittorio Grimaldi Christian De Vita Deepak K. Sharma Isabelle Gallet

Densely integrated photonic integrated circuits (PICs) require efficient solutions for monitoring the light intensity on chip in order to implement control and configuration operations to set and stabilize the working point of the circuit. To this end, waveguides supporting the propagation of surface plasmon polaritons (SPPs) are good candidates to realize small-footprint light detectors. In this work, we report on the realization of an in-line Surface Plasmon Detector (SPD) that exploits the photothermal effect to monitor the optical power in a titanium dioxide (TiO2) optical waveguide. Detailed design guidelines are provided to maximize the responsivity of the SPD, taking into account the effects of the metal geometry on the coupling between the dielectric and plasmonic modes, the power dissipated in the metal, and the equivalent thermal resistance of the structure. Experimental validation of the proposed device is provided demonstrating an ultra-compact 1.6-

$\mu \text{m}$

-long SPD operating at a wavelength of 1550 nm with a sensitivity of–20 dBm and a bandwidth higher than 100 kHz. The proposed device concept can be ported to generic dielectric platforms and to other wavelength ranges where SPP propagation is supported.

Exploring 10 Gb/s transmissions in Titanium dioxide based waveguides at 1.55 pm and 2.0 pm

Manon Lamy Christophe Finot Julien Fatome Juan Arocas Jean‐Claude Weeber

Summary form only given. Exploring new spectral bands for optical transmission is one of the solutions to support the increasingly demand of data traffic. The recent development of dedicated hollow-core photonic bandgap fibers [1], associated to the emergence of thulium doped fiber amplifiers [2] has recently focused the attention further in the infrared, and more specifically around 2 μm. Regarding integrated photonics, it becomes therefore interesting to find a suitable platform to operate at 2 μm as well as in the other more conventional spectral bands (going from 800 nm to 1550 nm). Here, we propose titanium dioxide (TiO ₂ ) as a good candidate for integrated waveguide photonics and demonstrate, for the first time, high bit rate transmissions at 1550 nm and 1980 nm.

Phase Evolution of Peregrine-Like Solitons in Nonlinear Fiber Optics

Gang Xu Kamal Hammani Amin Chabchoub John M. Dudley Bertrand Kibler

Optical fiber systems are well-known to provide convenient platforms in which one may investigate a large variety of fascinating fundamental nonlinear coherent structures such as solitons or self-similar patterns. Interestingly, one of the major conclusions of the studies dealing with extreme-value fluctuations is that the temporal and spectral characteristics of localization processes can be well described in terms of solitons over finite background and in particular in terms of Peregrine soliton (PS) [1]. Whereas the longitudinal evolution of the temporal and spectral intensity of the PS have been characterized in detail [2], much less attention has been experimentally devoted to the evolution of its phase properties. We report here a study that complements the analysis of the nonlinear dynamics of this coherent structure: by exploring the longitudinal evolution of the temporal phase profile and the phase difference Δφ between the central part of the pulse and the continuous background, we experimentally confirm some important features of the PS [3].

Rediscovered dynamics of nonlinear fiber optics: from breathers to extreme localisation

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2011)

Bertrand Kibler Julien Fatome Christophe Finot Kamal Hammani G. Millot

Recent investigations in nonlinear fiber optics have shown a renewed interest in certain classes of analytical solutions of the Nonlinear Schrödinger equation which, although present in the mathematical literature for 25 years, have been largely overlooked in studies of nonlinear fiber propagation. In this paper we review recent experiments that have shown the power of this analytic approach.

We demonstrate an error-free transmission of 10-Gbit/s optical signals along a SiGe waveguide at a wavelength of 1.98 μm. Bit error rate measurements confirm the absence of penalty during the transmission through a 2.5-cm long waveguide having a width of 2.2 μm.

Spectroscopie à deux peignes de fréquences électro-optiques pour la mesure de rapports isotopiques

Photoniques (2023)

Alexandre Parriaux Kamal Hammani G. Millot

Nous montrons que la spectroscopie à double peignes électro-optiques permet de mesurer le rapport isotopique 13 C/ 12 C avec une précision meilleure que 2‰ pour un temps d’enregistrement de quelques dizaines de secondes. Les résultats sont compatibles avec des mesures obtenues à l’aide d’un spectromètre de masse.
