Specular reflection and transmission of electromagnetic waves by disordered metasurfaces

Kevin Vynck, Armel Pitelet, Louis Bellando +1

Planar, disordered assemblies of small particles incorporated in layered media -- sometimes called ``disordered metasurfaces'' in the recent literature -- are becoming widespread i…

Active rejection-enhancement of spectrally adaptive liquid crystal geometric phase vortex coronagraphs

N. Kravets, U. Mur, M. Ravnik +2

Geometric phase optical elements made of space-variant anisotropic media customarily find their optimal operating conditions when the half-wave retardance condition is fulfilled, w…

Chiral Discrimination in Helicity-Preserving Fabry-Pérot Cavities

L. Mauro, J. Fregoni, J. Feist +1

We theoretically study circular dichroism of chiral molecules embedded inside a helicity-preserving Fabry-Pérot cavity. We find an increase of the intrinsic chiroptical response of…

Optimal Cooling of Multiple Levitated Particles: Theory of Far-Field Wavefront-Shaping

Jakob Hüpfl, Nicolas Bachelard, Markus Kaczvinszki +3

The opportunity to manipulate small-scale objects pushes us to the limits of our understanding of physics. Particularly promising in this regard is the interdisciplinary field of l…

Ultrafast Polarization-Tunable Monochromatic Extreme Ultraviolet Source at High-Repetition-Rate

Antoine Comby, Debobrata Rajak, Dominique Descamps +5

We report on the development of a high-order harmonic generation (HHG)-based ultrafast high-repetition-rate (250 kHz) monochromatic extreme ultraviolet (21.6 eV) source with polari…

Giant diffusion of nanomechanical rotors in a tilted washboard potential

Louis. Bellando, Melissa. Kleine, Yacine. Amarouchene +2

We present an experimental realization of a biased optical periodic potential in the low friction limit. The noise-induced bistability between locked (torsional) and running (spinn…

Control of nonlinear processes using versatile random photonic sources: Application to the energy deposition in a dielectric material

Denis Marion, Jean-Christophe Delagnes, Guillaume Duchateau

We report on the properties of a non-conventional stochastic photonic source. We first describe the principle of nonlinear intensity filtering by using a modified Mach-Zehnder inte…

Phase-matched high-order harmonic generation in pre-ionized noble gases

O. Finke, J. Vábek, M. Nevrkla +8

One of the main difficulties to efficiently generating high-order harmonics in long neutral-gas targets is to reach the phase-matching conditions. One issue is that the medium cann…
