Experimental Demonstration of Fractional Orbital Angular Momentum Entanglement of Two Photons
Experimental Demonstration of Fractional Orbital Angular Momentum Entanglement of Two Photons
The singular nature of a non-integer spiral phase plate allows easy manipulation of spatial degrees of freedom of photon states. Using two such devices, we have observed very high dimensional (D > 3700) spatial entanglement of twin photons generated by spontaneous parametric down-conversion.
