    "abstract": "An oscillatory correlation function has been observed by the coincidence\ncounting of multimode two-photon pairs produced with a degenerate optical\nparametric oscillator far below threshold. The coherent superposition of the\nmultimode two-photon pairs provides the oscillation in the intensity\ncorrelation function. The experimental data are well fitted to a theoretical\ncurve.",
