Brazilian Twin Photons 32nd anniversary
Renné Medeiros de Araújo, Raphael César Souza Pimenta, Lucas Marques Fagundes +4
We present a historical review of the development and impact of spontaneous parametric down-conversion (SPDC) in Brazil, marking over three decades since the first twin-photon expe…
Experimental investigation of the role of spatial correlations in optical integration with heralded single photons
L. Marques Fagundes Silva, R. C. Souza Pimenta, M. H. Magiotto +4
In this work, we demonstrate optical integration using heralded single photons and explore the influence of spatial correlations between photons on this process. Specifically, we e…
Experimental Investigation of Twist Conservation in Nonlinear Optical Three-Wave Mixing
Gustavo H. dos Santos, André L. S. Santos Junior, Marcos Gil de Oliveira +7
We conduct an experimental investigation into the conservation of the twist phase in Twisted Gaussian Schell Model (TGSM) beams during both up- and down-conversion three-wave mixin…
Discrimination of vortex and pseudovortex beams with a triangular optical cavity
L. Marques Fagundes, P. H. Souto Ribeiro, R. Medeiros de Araújo
A triangular optical cavity can be used to distinguish between two beams with the same intensity profile but different wavefronts. This is what we show in this paper, both theoreti…
Decomposing spatial mode superpositions with a triangular optical cavity
G. H. dos Santos, D. C. Salles, M. G. Damaceno +5
We demonstrate that a triangular cavity can operate as an efficient discriminator for Hermite-Gaussian optical modes. The process is applied to distinct fields produced by a Spatia…
Full Thermalization of a Photonic Qubit
A. G. de Oliveira, R. M. Gomes, V. C. C. Brasil +3
The generalized amplitude damping (GAD) quantum channel implements the interaction between a qubit and an environment with arbitrary temperature and arbitrary interaction time. Her…
Quantum-optical Description of Phase Conjugation of Vector Vortex Beams in Stimulated Parametric Down Conversion
A. G. de Oliveira, N. Rubiano da Silva, R. Medeiros de Araújo +2
We present a quantum optics approach for describing stimulated parametric down conversion in the two type-I crystal "sandwich" configuration, which allows for parametric interactio…
Real-time Phase Conjugation of Vector Vortex Beams
A. G. de Oliveira, M. F. Z. Arruda, W. C. Soares +4
Vector vortex beams have played a fundamental role in the better understanding of coherence and polarization. They are described by spatially inhomogeneous polarization states, whi…
