Observation of Replica Symmetry Breaking in Filamentation and Multifilamentation
André C. A. Siqueira, Guillermo Palacios, Jessica E. Q. Bautista +4
We report the experimental observation and characterization of Replica Symmetry Breaking (RSB) manifestation while analyzing the transverse intensity profile of pulses in filamenta…
Multiple Temporal Compression as a method to control the generation of bright and dark solitons
André C. A. Siqueira, Palacios G., Mario B. Monteiro +4
Recently published works have shown that the Multiple Temporal Compression (MTC) method is a more efficient approach for generation of multiple bright solitons in stacked waveguide…
Generation of robust temporal soliton trains by the multiple-temporal-compression (MTC) method
André C. A. Siqueira, Guillermo Palacios, Albert S. Reyna +3
We report results of systematic numerical analysis for multiple soliton generation by means of the recently reported multiple temporal compression (MTC) method, and compare its eff…
Observation and analysis of creation, decay, and regeneration of annular soliton clusters in a lossy cubic-quintic optical medium
Albert S. Reyna, Henrique T. M. C. M. Baltar, Emeric Bergmann +5
We observe and analyze formation, decay, and subsequent regeneration of ring-shaped clusters of (2+1)-dimensional spatial solitons (filaments) in a medium with the cubic-quintic (f…
Photonic ferromagnetic-like spontaneous mode-locking phase transition with replica symmetry breaking in multimode Nd:YAG laser
André L. Moura, Pablo I. R. Pincheira, Ernesto P. Raposo +2
The recent reports of the replica symmetry breaking (RSB) phenomenon in photonic experiments [1-5] boosted the understanding of the role of disorder in multimode lasers, as well as…
Robust self-trapping of vortex beams in a saturable optical medium
Albert S. Reyna, Georges Boudebs, Boris A. Malomed +1
We report the first observation of robust self-trapping of vortex beams propagating in a uniform condensed medium featuring local saturable self-focusing nonlinearity. Optical vort…
Stability conditions for one-dimensional optical solitons in cubic-quintic-septimal media
Albert S. Reyna, Boris A. Malomed, Cid B. de Araujo
Conditions for stable propagation of one-dimensional bright spatial solitons in media exhibiting optical nonlinearities up to the seventh-order are investigated. The results show w…
Nonlinearity management of photonic composites and observation of spatial-modulation instability due to quintic nonlinearity
Albert S. Reyna, Cid B. de Araújo
We present a procedure for nonlinearity management of metal-dielectric composites. Varying the volume fraction occupied by silver nanoparticles suspended in acetone we could cancel…
