Abstract
Structured correlations are important for quantum imaging. We propose and experimentally demonstrate a method to structure spatial two-photon correlations in the near-field by controlling phase-matching. Entanglement witnessed in the near-field enables these structured two-photon correlations to be useful for entanglement-based applications.
