Extending the capabilities of vectorial ptychography to circular-polarizing materials such as cholesteric liquid crystals

Patrick Ferrand, Michel Mitov

The problem of imaging materials with circular polarization properties is discussed within the framework of vectorial ptychography. We demonstrate, both theoretically and numerical…

Multipartite Entanglement in Bright Frequency Combs from Microresonators

Adrien Bensemhoun, C Gonzalez-Arciniegas, Olivier Pfister +6

We present a theoretical model of multimode quantum correlations in bright frequency combs generated in continuous-wave regime by microresonators above threshold. Our analysis show…

Bound states in the continuum induced via local symmetries in complex structures

Cheng-Zhen Wang, Ulrich Kuhl, Adin Dowling +2

Bound states in the continuum (BICs) defy conventional wisdom that assumes a spectral separation between propagating waves, that carry energy away, and spatially localized waves co…

Rayleigh-Jeans thermalization vs beam cleaning in multimode optical fibers

Kilian Baudin, Josselin Garnier, Adrien Fusaro +4

Classical nonlinear waves exhibit, as a general rule, an irreversible process of thermalization toward the Rayleigh-Jeans equilibrium distribution. On the other hand, several recen…

Topological constraints on the dynamics of vortex formation in a two-dimensional quantum fluid

Thibault Congy, Pierre Azam, Robin Kaiser +1

We present experimental and theoretical results on formation of quantum vortices in a laser beam propagating in a nonlinear medium. Topological constrains richer than the mere cons…

Near-infrared dual-comb spectroscopy of CO2 and N2O with a discretized highly nonlinear fiber

Alix Malfondet, Moise Deroh, Sidi-Ely Ahmedou +9

In this paper, we introduce an all-fibered dual-comb spectrometer based on a new design of highly nonlinear fiber to efficiently convert frequency combs from 1.55 micron to 2 micro…

Compressed Sensing of Field-resolved Molecular Fingerprints Beyond the Nyquist Frequency

Kilian Scheffter, Jonathan Will, Claudius Riek +4

Ultrashort time-domain spectroscopy and field-resolved spectroscopy of molecular fingerprints are gold standards for detecting samples' constituents and internal dynamics. However,…

Noise-induced broadening of a quantum-dash laser optical frequency comb

Aleksei I. Borodkin, Anton V. Kovalev, Massimo Giudici +4

Single-section quantum dash semiconductor lasers have attracted much attention as an integrated and simple platform for the generation of THz-wide and flat optical frequency combs…

An effective semilocal model for wave turbulence in 2D nonlinear optics

Jonathan Skipp, Jason Laurie, Sergey Nazarenko

The statistical evolution of ensembles of random, weakly-interacting waves is governed by wave kinetic equations. To simplify the analysis, one frequently works with reduced differ…

Coherence build up and laser thresholds from nanolasers to macroscopic lasers

Mark Anthony Carroll, Giampaolo D'Alessandro, Gian Luca Lippi +2

We detail the derivation of nanolaser models that include coherent and incoherent variables and predict the existence of a laser threshold, irrespective of cavity size and emitter…

Observation of light thermalization to negative temperature Rayleigh-Jeans equilibrium states in multimode optical fibers

K. Baudin, J. Garnier, A. Fusaro +5

Although the temperature of a thermodynamic system is usually believed to be a positive quantity, under particular conditions, negative temperature equilibrium states are also poss…
