It is shown theoretically that when the light produced by spontaneous parametric downconversion is mixed with a stationary, narrow-band local oscillator field centered on the mid-frequency, the resulting optical field exhibits photon antibunching in the steady state. The treatment is based on the integration of the coupled Heisenberg equations of motion for the field modes.
