“…This may cause some issues related to the fact that we can no longer consider this a linear imaging measurement, and the nonlinearity may lead to deformations of the various object planes [32]. We did, however, experimentally verify that objects placed at the cell input could be imaged through the sample and that distortions appeared to be significant only in the presence of sharp transitions from very low to very high light intensity regions.…”

Quantum gases of atoms and exciton-polaritons are now well-established theoretical and experimental tools for fundamental studies of quantum many-body physics and suggest promising applications to quantum computing. Given their technological complexity, it is of paramount interest to devise other systems where such quantum many-body physics can be investigated at lesser technological expense. Here we examine a relatively well-known system of laser light propagating through thermo-optical defocusing media: based on a hydrodynamic description of light as a quantum fluid of interacting photons, we investigate such systems as a valid room-temperature alternative to atomic or exciton-polariton condensates for studies of many-body physics. First, we show that by using a technique traditionally used in oceanography it is possible to perform a direct measurement of the single-particle part of the dispersion relation of the elementary excitations on top of the photon fluid and to detect its global flow. Then, using a pump-and-probe setup, we investigate the dispersion of excitation modes of the fluid: for very long wavelengths, a sonic, dispersionless propagation is observed that we interpret as a signature of superfluid behavior.

“…The measurements are performed with a linear optical sampling setup [24] which enables us to record the nonlinear evolution of the signal power profile with high temporal resolution over the complete propagation distance. Such a detailed experimental insight in nonlinear pulse propagation in discrete systems is, at present, unattainable in equivalent spatial arrangements [5,6,25].…”

Optical Gap solitons and Truncated Nonlinear Bloch Waves in Temporal Lattices

We experimentally demonstrate the formation and stable propagation of various types of discrete temporal solitons in an optical fiber system. Pulses interacting with a time-periodic potential and defocusing nonlinearity are shown to form gap solitons and nonlinear truncated Bloch waves. Multipulse solitons with defects, as well as novel structures composed of a strong soliton riding on a weaker truncated nonlinear Bloch wave are shown to propagate over up to eleven coupling lengths. The nonlinear dynamics of all pulse structures is monitored over the full propagation distance which provides detailed insight into the soliton dynamics.

“…Several techniques have been demonstrated, including image transmission based on phase conjugation [1], incoherent soliton waveguides [2], and digital holography [3]. Recently, image transmission based on coherent destruction of tunneling has also been demonstrated [4,5].…”

We demonstrate both theoretically and experimentally that photonic lattices under self-defocusing nonlinearity support gap solitons in various shapes such as cross and H shapes. These solitons, with their intensity humps all in-phase, are stable against perturbations, thus they propagate robustly throughout the lattices. Based on this finding, we propose soliton-based text/image transmission through bulk photonic structures.
