Characterization of spatiotemporal chaos in a Kerr optical frequency comb and in all fiber cavities Liu, Z.; Ouali, M.; Coulibaly, S.; Clerc Gavilán, Marcel; Taki, M.; Tlidi, M. (OSA - The Optical Society, 2017)Complex spatiotemporal dynamics have been a subject of recent experimental investigations in optical frequency comb microresonators and in driven fiber cavities with Kerr-type media. We show that this complex behavior has ...

Clerc Gavilán, Marcel; Ferre, M. A.; Coulibaly, S.; Rojas, R. G.; Tlidi, M. (Optical Society of America, 2017)We consider coupled-waveguide resonators subject to optical injection. The dynamics of this simple device are described by the discrete Lugiato-Lefever equation. We show that chimera-like states can be stabilized, thanks ...

Experimental observation of front propagation in a negatively diffractive inhomogeneous Kerr cavity Odent, Vincent; Tlidi, M.; Clerc Gavilán, Marcel; Glorieux, P.; Louvergneaux, E. (American Physical Society, 2014)A focusing Kerr Fabry-P´erot cavity operating in a negative diffraction regime exhibits transverse propagating fronts connecting two different nematic liquid crystal molecule average orientations. Under an inhomogeneous spatial ...

Tlidi, M.; Berríos Caro, E.; Pinto Ramo, D.; Vladimirov, A. G; Clerc Gavilán, Marcel (Elsevier, 2020)The dynamics of ecological systems are often described by integrodifferential equations that incorporate nonlocal interactions associated with facilitative, competitive interactions between plants, and seed dispersion. In ...

Clerc Gavilán, Marcel; Coulibaly, S.; Parra Rivas, P.; Tlidi, M. (American Institute of Physics, 2020)A ring resonator made of a silica-based optical fiber is a paradigmatic system for the generation of dissipative localized structures or dissipative solitons. We analyze the effect of the non-instantaneous nonlinear response ...

Tlidi, M.; Clerc Gavilán, Marcel; Escaff, D.; Couteron, P.; Messaoudi, M.; Khaffou, M.; Makhoute, A. (Royal Society Publishing, 2018)We report for the first time on the formation of spirals like vegetation patterns in isotropic and uniform environmental conditions. The vegetation spirals are not waves and they do not rotate. They belong to the class of ...

Berríos Caro, Ernesto; Clerc Gavilán, Marcel; Escaff, D.; Sandivari Gana, Camila; Tlidi, M. (Nature, 2020)Fragmentation followed by desertification in water-limited resources and/or nutrient-poor ecosystems is a major risk to the biological productivity of vegetation. By using the vegetation interaction-redistribution model, ...

Patchy landscapes in arid environments: Nonlinear analysis of the interaction-redistribution model Messaoudi, M.; Clerc Gavilán, Marcel; Berríos Caro, Ernesto; Pinto Ramos, D.; Khaffou, M.; Makhoute, A.; Tlidi, M. (American Institute of Physics, 2020)We consider a generic interaction-redistribution model of vegetation dynamics to investigate the formation of patchy vegetation in semi-arid and arid landscapes. First, we perform a weakly nonlinear analysis in the ...

Alvarez Socorro, A.; Clerc Gavilán, Marcel; Tlidi, M. (American Institute of Physics Inc., 2018)We consider a paradigmatic nonvariational scalar Swift-Hohenberg equation that describes short wavenumber or large wavelength pattern forming systems. This work unveils evidence of the transition from stable stationary to ...

Clerc Gavilán, Marcel; Coulibaly, S.; Ferré, M. A.; Tlidi, M. (American Institute of Physics, 2020)Two-dimensional arrays of coupled waveguides or coupled microcavities allow us to confine and manipulate light. Based on a paradigmatic envelope equation, we show that these devices, subject to a coherent optical injection, ...
