Abstract

We examine the spatial correlation of thermal-light diffracted through a double-slit using photon-number-resolved detection to directly measure high-order correlations. We observe sinusoidal modulations of the spatial coherence in the diffracted light field. The fringe width can be made arbitrarily small theoretically, and experimentally, we have obtained fringe widths as small as 30 nm.
