    "abstract": "The \u0027Ghost\u0027 interference experiment is analyzed when the source of entangled\nphotons is a multimode Optical Parametric Amplifier(OPA) whose weak limit is\nthe two-photon Spontaneous Parametric Downconversion(SPDC) beam. The visibility\nof the double-slit pattern is calculated, taking the finite coincidence time\nwindow of the photon counting detectors into account. It is found that the\ncoincidence window and the bandwidth of light reaching the detectors play a\ncrucial role in the loss of visibility on coincidence detection, not only in\nthe \u0027Ghost\u0027 interference experiment but in all experiments involving\ncoincidence detection. The differences between the loss of visibility with\ntwo-mode and multimode OPA sources is also discussed.\n  PACS: 42.65.Yj, 42.50.Dv, 42.65.Lm",
