Bm. Jost et al., SPATIAL CORRELATIONS OF SPONTANEOUSLY DOWN-CONVERTED PHOTON PAIRS DETECTED WITH A SINGLE-PHOTON-SENSITIVE CCD CAMERA, OPTICS EXPRESS, 3(2), 1998, pp. 81-88
A single-photon-sensitive intensified charge-coupled-device (ICCD) cam
era has been used to simultaneously detect, over a broad area, degener
ate and nondegenerate photon pairs generated by the quantum-optical pr
ocess of spontaneous parametric down-conversion. We have developed a n
ew method for determining the quantum fourth-order correlations in spa
tially extended detection systems such as this one. Our technique reve
als the expected phase-matching-induced spatial correlations in a 2-f
Fourier-transform system. (C) 1998 Optical Society of America.
