Author:McLaren, M; Romero, J; Giovannini, D; Galvez, EJ; Padgett, MJ; Forbes, ADate:Jul 2013Typically, a Gaussian mode is used to pump a non-linear crystal to produce pairs of entangled photons. We demonstrate orbital angular momentum (OAM) entanglement when a non-fundamental mode is used to pump a non-linear crystal. An approximation ...Read more
Author:Zhang, Y; Mclaren, M; Roux, FS; Forbes, ADate:Jul 2014We present a simple method of simulating the effect of the pumping process in spontaneous parametric down-conversion (SPDC) by modulating a classical laser beam with two spatial light modulators through a back projection setup. We simulate a ...Read more
