15. Recently M. Atatüre [Phys. Rev. Lett. 84, 618 (2000)] claimed that one can recover high-visibility quantum interference in pulse pumped type-II SPDC from a thick crystal without spectral postselection (by using narrow-band spectral filters). The theory as well as the interpretation of the experimental data presented their work are, however, shown to be in error;see Y.-H. Kim, S.P. Kulik, M.H. Rubin, and Y.H. Shih, Phys. Rev. Lett. (to be published).

22. The visibility factor V is in general a function of (Formula presented) where (Formula presented) is the group velocity of the ordinary ray, (Formula presented) the pump pulse duration, and the delay T. Note that V is not a function of bandwidths of the spectral filters. One can also prepare a Bell state using two type-II SPDC. Equation (7) still remains valid, but the function V has a different width and shape. See Ref. 16.

24. The bandwidth of the spectral filter is 10 nm at full width half maximum. This is comparable to the spectrum bandwidth of type-I nondegenerate SPDC, which is (Formula presented) nm for the crystals used in the experiment.
