Hybrid patterns and solitonic frequency combs in non-Hermitian Kerr Cavities
Salim B. Ivars, Carles Milián, Muriel Botey +2
We unveil a new scenario for the formation of dissipative localised structures in nonlinear systems. Commonly, the formation of such structures arises from the connection of a homo…
Non-Hermitian arrangement for stable semiconductor laser arrays
J. Medina Pardell, R. Herrero, M. Botey +1
We propose and explore a physical mechanism for the stabilization of the complex spatiotemporal dynamics in arrays (bars) of broad area laser diodes taking advantage of the symmetr…
Self-induced Faraday instability laser
A. M. Perego, S. V. Smirnov, K. Staliunas +2
We predict the onset of self-induced parametric or Faraday instabilities in a laser, spontaneously induced by the presence of pump depletion in the cavity, which leads to a periodi…
Formation of high-order acoustic Bessel beams by spiral diffraction gratings
Noé Jiménez, Rubén Picó, Víctor Sánchez-Morcillo +3
The formation of high-order Bessel beams by a passive acoustic device consisting of an Archimedes' spiral diffraction grating is theoretically, numerically and experimentally repor…
Pattern generation by dissipative parametric instability
A. M. Perego, N. Tarasov, D. V. Churkin +2
Nonlinear instabilities are responsible for spontaneous pattern formation in a vast number of natural and engineered systems ranging from biology to galaxies build-up. We propose a…
Taming of Modulation Instability by Spatio-Temporal Modulation of the Potential
S. Kumar, R. Herrero, M. Botey +1
Spontaneous pattern formation in a variety of spatially extended nonlinear system always occurs through a modulation instability: homogeneous state of the system becomes unstable w…
Acoustic Bessel-like beam formation by an axisymmetric grating
N. Jiménez, V. Romero-García, R. Picó +5
We report Bessel-like beam formation of acoustic waves by means of an axisymmetric grating of rigid tori. The results show that the generated beam pattern is similar to that of Bes…
High-Directional Wave Propagation in Periodic Gain/Loss Modulated Materials
N. Kumar, M. Botey, R. Herrero +2
Amplification/attenuation of light waves in artificial materials with a gain/loss modulation on the wavelength scale can be sensitive to the propagation direction. We give a numeri…
