Delocalized Correlations in Twin Light Beams with Orbital Angular Momentum
Alberto M. Marino, Vincent Boyer, Raphael C. Pooser, Paul D. Lett, Kristin Lemons, Kevin Jones
We generate intensity-difference-squeezed Laguerre-Gauss twin beams carrying orbital angular momentum using 4-wave mixing (4WM) in a hot atomic vapor. The conservation of orbital angular momentum in the 4WM process is studied as well as the spatial distribution of the quantum correlations obtained with different configurations of orbital angular momentum. Intensity-difference squeezing of up to 6.7 dB is demonstrated with beams carrying orbital angular momentum and delocalized spatial correlations are observed.
