Wavelength-adaptive spin-orbit orbital angular momentum management in three-wave mixing
Kiki Dekkers, Mwezi Koni, Vagharshak Hakobyan +5
Here we propose the use of an adjustable liquid crystal spin-orbit device to shape bi-colour structured light to create bimodal states. We demonstrate the proof-of-principle for tw…
Overcoming the surface paradox: Buried perovskite quantum dots in wide-bandgap perovskite thin films
Hao Zhang, Altaf Pasha, Isaac Metcalf +25
Colloidal perovskite quantum dots (PQDs) are an exciting platform for on-demand quantum, and classical optoelectronic and photonic devices. However, their potential success is limi…
Complementary Speckle STED Microscopy
Payvand Arjmand, Samlan Chandran Thodika, Elsa Bivas +5
Stimulated Emission Depletion (STED) microscopy has emerged as a powerful technique providing visualization of biological structures at the molecular level in living samples. In th…
Classical Approaches to Chiral Polaritonics
L. Mauro, J. Fregoni, J. Feist +1
We provide a theoretical framework based on classical electromagnetism, to describe optical properties of Fabry-Pérot cavities, filled with multilayered and linear chiral materials…
Roadmap on structured waves
K. Y. Bliokh, E. Karimi, M. J. Padgett +47
Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave.…
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…
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…
Optimal Cooling of Multiple Levitated Particles through Far-Field Wavefront-Shaping
Jakob Hüpfl, Nicolas Bachelard, Markus Kaczvinszki +3
Light forces can be harnessed to levitate mesoscopic objects and cool them down towards their motional quantum ground state. Significant roadblocks on the way to scale up levitatio…
Nonequilibrium dynamics induced by scattering forces for optically trapped nanoparticles in strongly inertial regimes
Yacine Amarouchene, Matthieu Mangeat, Benjamin Vidal Montes +4
As a first approximation, the forces acting on optically trapped particles are commonly assumed to be conservative. The influence of the nonconservative force has been shown to be…
Electrically-activated spin-controlled orbital angular momentum multiplexer

We present and test the integration of a static orbital angular momentum mode multiplexer with a dynamical geometric-phase optical element enabling on-demand spin-controlled angula…

Hernando Magallanes, Etienne Brasselet
Observing and taming unusual effects arising from non-trivial light-matter interaction has always triggered scientists to better understand Nature and develop technological tools t…

Mushegh Rafayelyan, Gonzague Agez, Etienne Brasselet
The realization of geometric phase optical device operating over a broad spectral range is usually confronted with intrinsic limitations depending of the physical process at play.…

O. Lozan, M. Perrin, B. Ea-Kim +3
In this work, we study the heat dissipated at metal surfaces by the electromagnetic field scattered by isolated subwavelength apertures in metal screens. In contrast to our common…
