Photon pairs generated by spontaneous four-wave mixing (FWM) in atomic ensembles provide a natural path toward quantum light-matter interfaces. They are intrinsically compatible with atomic quantum memories and can be entangled in different degrees of freedom, such as in orbital angular momentum (OAM), resulting in entangled qudits. We present our experimental studies for optimizing the semi-classical FWM in an elongated cold atomic ensemble of cesium (Cs) atoms as a step toward the efficient generation of entangled photons from spontaneous FWM.
