Optimal Diffractive Focusing of Vortex Beams
Roohollah Ghobadi, Carrie Rodriguez, Lukas Scarfe +2
We formulate diffractive ring focusing of paraxial beams carrying orbital angular momentum (OAM) through a finite circular aperture as a variational optimization problem. For a fix…
Transverse Distance Estimation with Higher-Order Hermite-Gauss modes
Dilip Paneru, Alessio D'Errico, Ebrahim Karimi
We explore the use of higher-order Hermite-Gauss modes for sensing optically induced transverse displacements. In the small-displacement regime, we show that projective measurement…
Compact and programmable large-scale optical processor in free space
Maria Gorizia Ammendola, Nazanin Dehghan, Lukas Scarfe +4
Photonic circuits are central to classical and quantum information processing. While integrated technologies dominate, free-space architectures are emerging as attractive alternati…
Spatially twisted liquid-crystal devices
Alicia Sit, Francesco Di Colandrea, Alessio D'Errico +1
Nematic liquid-crystal devices are a powerful tool to structure light in different degrees of freedom, both in classical and quantum regimes. Most of these devices exploit either t…
