Radial-angular coupling in self phase modulation with structured light
M. Gil de Oliveira, L. J. Pereira, A. S. Santos +3
In this work we study the evolution of an optical vortex undergoing self phase modulation inside a nonlinear Kerr medium. The intensity dependent phase evolution couples the angula…
Poincaré sphere symmetries in four-wave mixing with orbital angular momentum
Mateus Rattes Lima da Motta, Gabriel Bié Alves, Antonio Zelaquett Khoury +1
We explore a degenerate four-wave mixing process induced by transversely structured light beams in a rubidium vapor cell. In particular, we consider the nonlinear interaction drive…
Conservation of a Half-Integer Angular Momentum in Nonlinear Optics with a Polarization Möbius Strip
Martin Luttmann, Mekha Vimal, Matthieu Guer +5
Symmetries and conservation laws of energy, linear momentum and angular momentum play a central role in physics, in particular in nonlinear optics. Recently, light fields with non…
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…
Spin to orbital angular momentum transfer in nonlinear wave mixing
B. Pinheiro da Silva, W. T. Buono, L. J. Pereira +3
We demonstrate the spin to orbital angular momentum transfer in the nonlinear mixing of structured light beams. A vector vortex is coupled to a circularly polarized Gaussian beam i…
Transfer of angular spectrum in parametric down-conversion with structured light
Antonio Z. Khoury, Paulo H. Souto Ribeiro, Kaled Dechoum
We develop the formal approach to the angular spectrum transfer in parametric down-conversion that allows pumping with a structured beam. The scheme is based on an entangled photon…
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…
Orbital angular momentum mixing in type II second harmonic generation
Leonardo J. Pereira, Wagner T. Buono, Daniel S. Tasca +2
We investigate the non linear mixing of orbital angular momentum in type II second harmonic generation with arbitrary topological charges imprinted on two orthogonally polarized be…
Correlations in Electrically Coupled Chaotic Lasers
E. J. Rosero, W. A. S. Barbosa, J. F. Martinez Avila +2
We show how two electrically coupled semiconductor lasers having optical feedback can present simultaneous anti-phase correlated fast power fluctuations, and strong in-phase synchr…
