Synchronization of Synchrotron Radiation Bursts during a spatio-temporal Instability in accelerator-Based source
C. Evain, A. -A. Diallo, E. Roussel +9
Synchronization is a fundamental phenomenon in dynamical systems, occurring in a wide range of contexts such as mechanical, chemical, biological, and social systems. In this work,…
Cost-effective time-stretch terahertz recorders using 1550 nm probes
Christelle Hanoun, Eléonore Roussel, Christophe Szwaj +8
Time-stretch electro-optic detection allows THz waveforms to be recorded in single-shot, up to Megahertz acquisition rates. This capability is required in accelerator physics, and…
Topological properties of Floquet winding bands in a photonic lattice
Albert F. Adiyatullin, Lavi K. Upreti, Corentin Lechevalier +6
The engineering of synthetic materials characterised by more than one class of topological invariants is one of the current challenges of solid-state based and synthetic materials.…
Single shot measurement of the photonic band structure in a Floquet-Bloch lattice realised with coupled fiber rings
Corentin Lechevalier, Clément Evain, Pierre Suret +3
Floquet-Bloch lattices are systems in which wave packets are subjet to periodic modulations both in time and space, showing rich dynamics. While this type of lattices is difficult…
Topological swing in Bloch oscillations
L. K. Upreti, C. Evain, S. Randoux +3
We report new oscillations of wavepackets in quantum walks subjected to electric fields, that decorate the usual Bloch-Zener oscillations of insulators. The number of turning point…
Phase Diversity Electro-optic Sampling: A new approach to single-shot terahertz waveform recording
Eléonore Roussel, Christophe Szwaj, Bernd Steffen +4
THz spectroscopy is an emerging tool for detection of microorganisms and harmful compounds in the food industry, the study of proteins in biomedicine and the development of electro…
Floquet Winding Metals
Lavi Kumar Upreti, Clément Evain, Stephane Randoux +3
We propose a generic scattering matrix model implementable in photonics to engineer a new Floquet metallic phase that combines two distinct topological properties: the winding of t…
From self-organization in relativistic electron bunches to coherent synchrotron light: observation using a photonic time-stretch digitizer
Serge Bielawski, Edmund Blomley, Miriam Brosi +14
In recent and future synchrotron radiation facilities, relativistic electron bunches with increasingly high charge density are needed for producing brilliant light at various wavel…
Coherent Terahertz synchrotron radiation mastered by controlling the irregular dynamics of relativistic electron bunches
C. Evain, C. Szwaj, E. Roussel +9
Spontaneous formation of spatial structures (patterns) occurs in various contexts, ranging from sand dunes and rogue wave formation, to traffic jams. These last decades, very pract…
Direct observation of spatio-temporal dynamics of short electron bunches in storage rings
C. Evain, E. Roussel, M. Le Parquier +6
In recent synchrotron radiation facilities, the use of short (picosecond) electron bunches is a powerful method for producing giant pulses of Terahertz Coherent Synchrotron Radiati…
High sensitivity photonic time-stretch electro-optic sampling of terahertz pulses
Christophe Szwaj, Clément Evain, Marc Le Parquier +5
Single-shot recording of terahertz electric signals has recently become possible at high repetition rates, by using the photonic time-stretch electro-optic sampling (EOS) technique…
Direct observation of Rogue Waves in optical turbulence using Time Microscopy
Pierre Suret, Rebecca El Koussaifi, Alexey Tikan +4
The formation of coherent structures in noise driven phenomena and in Turbulence is a complex and fundamental question. A particulary important structure is the so-called Rogue Wav…
Observing microscopic structures of a relativistic object using a time -stretch strategy
E. Roussel, C. Evain, M. Le Parquier C. Szwaj +9
Emission of light by a single electron moving on a curved trajectory (synchrotron radiation) is one of the most well-known fundamental radiation phenomena. However experimental sit…
