Measurement of the orbital angular momentum density of light by modal decomposition

Author: Schulze, C ; Dudley, Angela L ; Flamm, D ; Duparre, M ; Forbes, A Date: Jul 2013 We demonstrate a versatile method for the measurement of the orbital angular momentum (OAM) density of an optical field. By performing a modal decomposition with digital holograms, we reconstruct the full optical field from a small set of ... Read more
Putting light in a spin

Author: Dudley, Angela L ; Rop, R ; Litvin, IA ; Lopez-Mariscal, C ; Roux, FS ; Forbes, A Date: Aug 2012 We experimentally generated superpositions of higher-order Bessel beams that possess no global orbital angular momentum (OAM), yet exhibit an angular rotation in their intensity profile as the field propagates. The digital holograms encoded ... Read more
Quantitatively measuring the orbital angular momentum density of light : Presentation

Author: Dudley, Angela L ; Schulze, C ; Litvin, I ; Duparré, M ; Forbes, A Date: Aug 2013 Although many techniques are efficient at measuring optical orbital angular momentum (OAM), they do not allow one to obtain a quantitative measurement for the OAM density across an optical field and instead only measure its global OAM. Numerous ... Read more
