Two-photon optics of Bessel-Gaussian modes
Melanie McLaren, Jacquiline Romero, Miles J. Padgett +2
In this paper we consider geometrical two-photon optics of Bessel-Gaussian modes generated in spontaneous parametric down-conversion of a Gaussian pump beam. We provide a general t…
Direct Measurement of a 27-Dimensional Orbital-Angular-Momentum State Vector
Mehul Malik, Mohammad Mirhosseini, Martin P. J. Lavery +3
The measurement of a quantum state poses a unique challenge for experimentalists. Recently, the technique of "direct measurement" was proposed for characterizing a quantum state in…
Optimising the use of detector arrays for measuring intensity correlations of photon pairs
Daniel S. Tasca, Matthew P. Edgar, Frauke Izdebski +2
Intensity correlation measurements form the basis of many experiments based on spontaneous parametric down-conversion. In the most common situation, two single-photon avalanche dio…
