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.…
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…
Electrically-activated spin-controlled orbital angular momentum multiplexer
Gianluca Ruffato, Etienne Brasselet, Michele Massari +1
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…
Tunable high-resolution macroscopic self-engineered geometric phase optical elements
Etienne Brasselet
Artificially engineered geometric phase optical elements may have tunable photonic functionalities owing to sensitivity to external fields, as is the case for liquid crystals based…
Macroscopic direct observation of optical spin-dependent lateral forces and left-handed torques
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…
Ultra-broadband gradient-pitch Bragg-Berry mirrors
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.…
