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…
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…
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…
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…
Tripartite non-separability in classical optics
W. F. Balthazar, C. E. R. Souza, D. P. Caetano +3
It is possible to prepare classical optical beams which cannot be characterized by a tensor product of vectors describing each of their degrees of freedom. Here we report the exper…
Spin-orbit mode transfer via a classical analog of quantum teleportation
B. Pinheiro da Silva, M. Astigarreta Leal, C. E. R. Souza +2
We translate the quantum teleportation protocol into a sequence of coherent operations involving three degrees of freedom of a classical laser beam. The protocol, which we demonstr…
