Dielectric geometric phase optical elements from femtosecond direct laser writing
Xuewen Wang, Aleksandr Kuchmizhak, Etienne Brasselet +1
We propose to use femtosecond direct laser writing technique to realize dielectric optical elements from photo-resist materials for the generation of structured light from purely g…
Photonic microwave signals with zeptosecond level absolute timing noise
Xiaopeng Xie, Romain Bouchand, Daniele Nicolodi +11
Photonic synthesis of radiofrequency revived the quest for unrivalled microwave purity by its seducing ability to convey the benefits of the optics to the microwave world. In this…
Vortex coronagraphy from self-engineered liquid crystal spin-orbit masks
Artur Aleksanyan, Etienne Brasselet
We report on a soft route towards optical vortex coronagraphy based on self-engineered electrically tunable vortex masks based on liquid crystal topological defects. These results…
Multiple scattering of polarized light in disordered media exhibiting short-range structural correlations
Kevin Vynck, Romain Pierrat, Rémi Carminati
We develop a model based on a multiple scattering theory to describe the diffusion of polarized light in disordered media exhibiting short-range structural correlations. Starting f…
Bragg-Berry mirrors: reflective broadband q-plates
Mushegh Rafayelyan, Etienne Brasselet
We report on the experimental realization of flat mirrors enabling the broadband generation of optical vortices upon reflection. The effect is based on the geometric Berry phase as…
