Phase-dependent photon statistics is observed in the mixed field of a narrow band two-photon source and a coherent field. At a certain phase, the nonclassical effect of photon antibunching occurs while at another the photon bunching effect appears. Furthermore, we observed a novel nonclassical phenomenon that exhibits more complex structure. The different features in photon statistics are attributed to a two-photon interference effect.

The quantum statistical behavior of a small collection of N two-state atoms strongly coupled to the field of a high-finessse optical cavity is investigated. Input-output characteristics are recorded over the range 3\ensuremath{\lesssim}N\ensuremath{\lesssim}65, with bistability observed for N\ensuremath{\gtrsim}15 intracavity atoms and for a saturation photon number ${\mathit{n}}_{0}$\ensuremath{\simeq}0.8. For weak excitation the transmitted field exhibits photon antibunching as a nonclassical manifestation of state reduction and quantum interference with the magnitude of the nonclassical effects largely independent of N.
