General diffraction properties of aperiodic slit arrays
Thiago de Souza Ferreira, Daniel Jonathan, Antonio Z. Khoury +1
Fraunhofer diffraction plays a vital role in experimental physics not only because it accurately describes the behaviour of light in the usual propagation limit, but also because i…
Coherence and Dimensionality Witnesses for Fractional OAM Modes
A. L. S. Santos Junior, I. Prego, M. Gil de Oliveira +5
We characterize sets of fractional orbital angular momentum (OAM) modes of a light beam using unitary-invariant properties encoded by two-mode overlaps. Using basis-independent coh…
Optimal beam displacement measurements using high-order structured light modes
A. L. S. Santos Junior, J. C. de Carvalho Junior, M. Gil de Oliveira +4
We develop a novel technique to measure small angular and lateral displacements of structured light beams. The technique relies on using high-order Hermite-Gaussian (HG) and Laguer…
Informationally Complete Orbital Angular Momentum Tomography with Intensity Measurements
M. Gil de Oliveira, A. L. S. Santos Junior, P. M. R. Lima +4
In this work we study the tomography of the spatial structure of light. We develop a simple technique that allows one to perform the tomography over the space of fixed order modes.…
Optical computing of quantum revivals
Mayanne R. Maia, Daniel Jonathan, Thiago R. Oliveira +2
Interference is the mechanism through which waves can be structured into the most fascinating patterns. While for sensing, imaging, trapping, or in fundamental investigations, stru…
Machine learning recognition of light orbital-angular-momentum superpositions
B. Pinheiro da Silva, B. A. D. Marques, R. B. Rodrigues +2
We developed a method to characterize arbitrary superpositions of light orbital angular momentum (OAM) with high fidelity by using astigmatic tomography and machine learning proces…
Pattern revivals from fractional Gouy phases in structured light
B. Pinheiro da Silva, V. A. Pinillos, D. S. Tasca +2
We investigate pattern revivals in specially designed optical structures that combine different transverse modes. In general, the resulting pattern is not preserved under free prop…
