Abstract
We present an experimental study of the entangled two-photon polarizat ion states in type-II optical parametric down-conversion. It is intere sting to see that the polarization entanglement depends on the detecti on spectral bandwidth, i.e., the bandwidth of the spectral filters pla ced in front of the detectors. The entanglement is also dependent on t he length of the down-conversion crystal. A simple quantum model is pr ovided to explain these phenomena.
