The effect of discrete-time evolution on thermalisation in a lattice
Thomas Moorcroft, Alberto Amo, François Copie +3
Particles subject to weak contact interactions in a finite-size lattice tend to thermalise. The Hamiltonian evolution ensures energy conservation and the final temperature is fully…
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…
Statistical properties of nonlinear stage of modulation instability in fiber optics
Adrien Kraych, Dmitry Agafontsev, Stephane Randoux +1
We present an optical fiber experiment in which we examine the space-time evolution of a modulationally unstable plane wave initially perturbed by a small noise. Using a recirculat…
Phase and Amplitude single-shot measurement by using heterodyne time-lens and ultrafast digital time-holography
Alexey Tikan, Serge Bielawski, Christophe Szwaj +2
Temporal imaging systems are outstanding tools for single-shot observation of optical signals that have irregular and ultrafast dynamics. They allow long time windows to be recorde…
Cooperative oscillation of non-degenerate transverse modes in an optical system: multimode operation in parametric oscillators
Axelle Amon, Pierre Suret, Serge Bielawski +2
We show experimentally that parametric interaction can induce a cooperative oscillation of non simultaneously resonant transverse modes in an optical parametric oscillator. More ge…
