Experimental scheme to investigate nonclassicality and nonlocality of light fields of disparate sources using spatial correlation functions — •Johannes Hölzl1,2, Ralph Wiegner1, Girish S.

We present an experimental scheme for a detection-efficient measurement of spatial two-photon correlations functions of light fields produced by statistically independent disparate sources. By using one single photon emitter, e.g., a spontaneous parametric down conversion source, and controlling the intensity of a second classical source the visibility of the correlation function can exceed the limit where classical Cauchy-Schwarz- and local-realistic Bell-type inequalities are violated.
