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…
Polychromatic Electric Field Knots
Manuel F. Ferrer-Garcia, Alessio D'Errico, Alicia Sit +2
The polarization of a monochromatic optical beam lies in a plane, and in general, is described by an ellipse, known as the polarization ellipse. The polarization ellipse in the tig…
Measuring the complex orbital angular momentum spectrum and spatial mode decomposition of structured light beams
Alessio D'Errico, Raffaele D'Amelio, Bruno Piccirillo +2
Light beams carrying orbital angular momentum are key resources in modern photonics. In many applications, the ability of measuring the complex spectrum of structured light beams i…
