Paper Abstract

Speckle structure1 of Parametric Down Conversion (PDC) has recently received a large attention due to the relevance in view of applications to quantum imaging. The possibility of tailoring the speckle size by acting on the pump intensity and dimensions is an interesting tool for the applications to quantum imaging and in particular to the detection of weak objects under shot-noise limit. In this paper we report a systematic detailed study of the speckle structure, in particular of the one in type II PDC, with attention to its variation with pump beam characteristics (power and radius).
