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 Mode Cleaning in Periodically Modulated Multimode Fibers
M. N. Akhter, S. B. Ivars, M. Botey +2
We show that the simultaneous modulation of the propagation constant and of the gain/loss coefficient along the multimode fibers results in unidirectional coupling among the modes,…
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…
Genetic optimization Invents non-Hermitian potentials for Asymmetric Reflectivity
W. W. Ahmed, R. Herrero, M. Botey +2
We propose a general design strategy based on genetic optimization to realize asymmetric reflectivity in periodic and non-periodic planar structures containing dielectric and gain-…
Restricted Hilbert transform for non-Hermitian management of fields
W. W. Ahmed, R. Herrero, M. Botey +2
Non-Hermitian systems exploiting the synergy between gain and loss have recently become the focus of interest to discover novel physical phenomena. The spatial symmetry breaking in…
Regularization of Vertical-Cavity Surface-Emitting Lasers emission by periodic non-Hermitian potentials
W. W. Ahmed, R. Herrero, M. Botey +2
We propose a novel physical mechanism based on periodic non-Hermitian potentials to efficiently control the complex spatial dynamics of broad-area lasers, particularly in Vertical-…
