Partial coherence and coherence length in StimPDC
Gustavo Henrique dos Santos, Raphael César Souza Pimenta, Rafael de Morais Gomes +2
In parametric down conversion, a nonlinear crystal is pumped by a laser and spontaneous emission takes place in signal and idler modes according to the phase matching conditions. A…
Machine learning recognition of light orbital-angular-momentum superpositions
B. Pinheiro da Silva, B. A. D. Marques, R. B. Rodrigues +2
We developed a method to characterize arbitrary superpositions of light orbital angular momentum (OAM) with high fidelity by using astigmatic tomography and machine learning proces…
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…
Klyshko's Advanced-Wave Picture in Stimulated Parametric Down-Conversion with a Spatially Structured Pump Beam
M. F. Z. Arruda, W. C. Soares, S. P. Walborn +4
The advanced-wave picture is "... an intuitive treatment of two-photon correlation with the help of the concept of an effective field acting upon one of the two detectors and forme…
Propagation of transverse intensity correlations of a two-photon state
D. S. Tasca, S. P. Walborn, F. Toscano +2
The propagation of transverse spatial correlations of photon pairs through arbitrary first-order linear optical systems is studied experimentally and theoretically using the fracti…
Image formation by manipulation of the entangled angular spectrum
D. P. Caetano, P. H. Souto Ribeiro
We demonstrate theoretical and experimentally how it is possible to manipulate an entangled angular spectrum of twin beams, in order to reconstruct correlated images with coinciden…
