Author:McLaren, M; Romero, J; Padgett, MJ; Roux, FS; Forbes, ADate:Sep 2013In 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 theoretical expression for the orbital angular momentum (OAM) ...Read more
