Extrinsic orbital angular momentum of entangled photon-pairs in spontaneous parametric down-conversion
Sheng Feng, Prem Kumar
Starting from the standard Hamiltonian describing the optical non-linear process of spontaneous parametric down-conversion, we theoretically show that the generated entangled photo…

Is orbital angular momentum always conserved in spontaneous parametric down-conversion?
Sheng Feng, Chao-Hsiang Chen, Geraldo A. Barbosa +1
In the non-linear optical process of type-II spontaneous parametric down-conversion, we present on an experiment showing that the two-photon detection amplitude of the down-convert…

The conservation of orbital angular momentum and the two-photon detection amplitude in spontaneous parametric down-conversion
Sheng Feng, Chao-Hsiang Chen, Geraldo A. Barbosa +1
We study the two-photon detection amplitude of the down-converted beams in spontaneous parametric down-conversion when the physical variable of orbital angular momentum is involved…
