Author:Dudley, Angela L; Nock, M; Konrad, T; Roux, FS; Forbes, ADate:Oct 2010In this article, the authors present an amplitude damping channel for Laguerre-Gaussian modes. The channel is tested experimentally for a Laguerre-Gaussian mode, having an azimuthal index l = 1, illustrating that it decays to a Gaussian mode ...Read more
Author:Romero, J; Giovannini, D; McLaren, MG; Galvez, EJ; Forbes, A; Padgett, MJDate:Aug 2012We report orbital angular momentum (OAM) and angle correlations between signal and idler photons observed when the nonlinear crystal used in spontaneous parametric down-conversion is illuminated by a non-fundamental Gaussian pump beam. We ...Read more
