Statistical mechanics demands that the temperature of a system is positive provided that its
internal energy has no upper bound. Yet if this condition is not met, it is possible to attain …

Photonic simulators using synthetic frequency dimensions have enabled flexible
experimental analogues of condensed-matter systems. However, so far, such photonic …

The chaotic evolution resulting from the interplay between topology and nonlinearity in
photonic systems generally forbids the sustainability of optical currents. Here, we …

Over the last few years, parity-time (PT) symmetry has been the focus of considerable
attention. Ever since, pseudo-Hermitian notions have permeated a number of fields ranging …

We reveal that a synthetic photonic lattice based on coupled optical loops can be utilized as
a feed-forward neural network for processing of optical pulse sequences in time domain. As …

We experimentally demonstrate the transverse confinement of light in the presence of a
longitudinally periodic photonic potential with vanishing average. In agreement with …

We study, to the best of our knowledge, the first observations of light propagation in synthetic
photonic lattice with anti-parity-time symmetry by tuning the gain or loss of two coupled fiber …

Synthetic dimensions have generated great interest for studying many types of topological,
quantum, and many-body physics, and they offer a flexible platform for simulation of …

L'objet des recherches de ce manuscrit est de caractériser la dynamique de la lumière dans
un réseau photonique. Les réseau photoniques sont des plateformes dans lesquels la …

We report the first experimental observation of optical thermodynamic processes in
nonlinear mesh photonic lattices. These include Rayleigh-Jeans distributions with either …
