Photon antibunching in pulsed squeezed light generated via parametric amplification. M. Koashi, K. Kono, T. Hirano and M. Matsuoka in Phys. Rev. Lett. 71:1164 (1993). What the paper says?
They implement the scheme of Stoler[1] to admix squeezed and coherent states but with pulsed excitation. Stoller's scheme was time-dependent and occurred in the transient anyway. They use the signal and pump of a degenerate parametric amplification.
They observed both bunching and antibunching depending on the phase relationship, as seen here for $g^{(2)}(\tau)$:
and here for $g^{(2)}(0)$ as a function of the intensity of mixing.
