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…

Theoretical investigation of moiré patterns in quantum images
M. P. Almeida, P. H. Souto Ribeiro, J. A. O. Huguenin +1
Moiré patterns are produced when two periodic structures with different spatial frequencies are superposed. The transmission of the resulting structure gives rise to spatial beatin…
