  We study continuous variable coherence of phase-dependent squeezed state
based on an extended Hanbury Brown-Twiss scheme. High-order coherence is
continuously varied by adjusting squeezing parameter $r$, displacement $\alpha
$, and squeezing phase $\theta $. We also analyze effects of background noise
$\gamma $ and detection efficiency $\eta $ on the measurements. As the
squeezing phase shifts from 0 to $\pi $, the photon statistics of the squeezed
state continuously change from the anti-bunching ($g^{(n)}<1$) to
super-bunching ($g^{(n)}>n!$) which shows a transition from particle nature to
wave nature. The experiment feasibility is also examined. It provides a
practical method to generate phase-dependent squeezed states with high-order
continuous-variable coherence by tuning squeezing phase $\theta $. The
controllable coherence source can be applied to sensitivity improvement in
gravitational wave detection and quantum imaging.
