The quantum correlation between a pair of photons, emitted by a Δ- type atom, is calculated. The correlation show anti-bunching property, and the second correlation function is dependent on classical field Ω. So we can control the magnitude of the joint detection probability by adjusting the driving field. In addition, Δ-type atom can also work as storage and retrieving apparatus.
