Spontaneous parametric down-conversion pumped by spatiotemporal structured light
Lukas Montenegro, Rafael F. Barros
Here we investigate the all-optical control of spectral correlations in spontaneous parametric down-conversion. We show that when photon pairs are projected onto high-order spatial…
Controlling quantum entanglement with classical non-separable light
R. F. Barros, A. L. S. Santos Junior, A. Z. Khoury +1
Here we investigate the quantum frequency conversion of entangled photons driven by a classically non-separable laser beam. We show that the frequency conversion dynamics is descri…
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…
Correlating space, wavelength, and polarization of light: Spatio-Spectral Vector Beams
Lea Kopf, Rafael Barros, Robert Fickler
Increasing the complexity of a light field through the advanced manipulation of its degrees of freedom (DoF) provides new opportunities for fundamental studies and technologies. Co…
Observation of the quantum Gouy phase
Markus Hiekkamäki, Rafael F. Barros, Marco Ornigotti +1
Controlling the evolution of a photonic quantum states is crucial for most quantum information processing and metrology tasks. Because of its importance, many mechanisms of quantum…
Generalized Orbital Angular Momentum Symmetry in Parametric Amplification
R. B. Rodrigues, G. B. Alves, R. F. Barros +2
We investigate interesting symmetry properties verified by the down-converted beams produced in optical parametric amplification with structured light. We show that the Poincaré sp…
Quantum-controlled cluster states
R. F. Barros, G. B. Alves, O. Pfister +1
Quantum optical cluster states have been increasingly explored, in the light of their importance for measurement-based quantum computing. Here we set forth a new method for generat…
Gouy-phase effects in the frequency combs of an optical parametric oscillator
R. F. Barros, G. B. Alves, A. Z. Khoury
We investigate the transverse mode effects on the frequency combs generated by a type-I optical parametric oscillator (OPO) below threshold. We take the diffraction effects fully i…
Fine-tuning of orbital angular momentum in an optical parametric oscillator
R. F. Barros, G. B. Alves, D. S. Tasca +2
We investigate the dynamical properties of a type-II optical parametric oscillator pumped by a structured light beam carrying orbital angular momentum. Different dynamical regimes…

G. B. Alves, R. F. Barros, D. S. Tasca +2
We investigate the transverse mode structure of the down-converted beams generated by a type-II optical parametric oscillator (OPO) driven by a structured pump. Our analysis focus…
