A Collective Propagation Law of Optical Vortex Constellations and Longitudinal Sensing
Niladri Modak, Rafael F. Barros, Marco Ornigotti +1
Optical vortices are ubiquitous phenomena naturally appearing in wave physics, yet higher-order charges inherently split into constellations of lowest-order singularities at the sm…
Faking entanglement with imperceptible measurement deviations
Jaime Moreno, Elna Svegborn, Simon Morelli +4
Quantum entanglement is a central resource underpinning emerging quantum technologies, enabling capabilities beyond those of classical systems. Accurate verification of entanglemen…
Tunable spatio-spectral Target Skyrmions and topological multiplexing
Pedro Ornelas, Niladri Modak, Oussama Korichi +3
Optical Skyrmions have recently garnered much interest providing a potential avenue for high capacity, robust topological information transfer. Typically, Skyrmions are derived fro…
Active control of phase matching in nonlinear metasurfaces using Pancharatnam--Berry phase
Madona Mekhael, Roman Calpe, Tommi K. Hakala +2
Reconfiguring the spectral output of nonlinear metasurfaces after fabrication remains challenging. We address this by exploiting the nonlinear Pancharatnam--Berry phase of …
Volumetric Processing of Structured Light Integrated in Glass
Oussama Korichi, Markus Hiekkamaki, Robert Fickler
Light with complex structures in polarization, phase and amplitude, has attracted a lot of attention in a broad range of applications and fundamental studies in classical and quant…
High-Dimensional Quantum Photonics: Roadmap
Mehul Malik, Micheal Kues, Takuya Ikuta +30
The field of high-dimensional quantum photonics involves the use of multimode photonic degrees-of-freedom such as the spatial, temporal, or spectral structure of light to encode mu…
