Structured light under turbulence
Guilherme S. Barros, Lucas C. Céleri, Antonio Zelaquett Khoury +3
Structured light has emerged as a promising resource for high-capacity and secure free-space optical communication, where atmospheric turbulence remains a major source of signal de…
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…
Spin-orbit implementation of Solovay-Kitaev decomposition of single-qubit channels
M. H. M. Passos, A. de Oliveira Junior, M. C. de Oliveira +2
The Solovay-Kitaev theorem allows us to approximate any single-qubit gate to arbitrary accuracy with a finite sequence of fundamental operations from a universal set of gates. Insp…
Conditions for optical parametric oscillation with structured light pump
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…
Phase conjugation and mode conversion in stimulated parametric down-conversion with orbital angular momentum: a geometrical interpretation
André G. de Oliveira, Marcelo F. Z. Arruda, Willamys C. Soares +5
We report on an experiment that investigates the spatial mode conversion in the process of parametric down-conversion seeded by a light beam in a superposition of orbital angular m…
Contextuality in spin-orbit laser modes
M. H. M. Passos, W. F. Balthazar, J. Acacio de Barros +3
We experimentally observed the violation of Kujula-Dzhafarov noncontextuality inequalities by non-separable spin-orbit laser modes. Qubits are encoded on polarization and transvers…
