High Q one dimensional photonic crystal cavity

I was trying to replicate a paper of one dimensional PhC in 3D FDTD

I have simulated the structure as given in the paper figure 3, with PML boundary conditions in all three directions as shown.

the transmission spectra that I got does not match figure 4, I am getting other peak except the peak having high Q factor. the Q factor that I am getting is 816, which is much below 10^7 as given in the paper. the transmission spectrum for my simulation is as shown

Please , tell what I am missing in my simulation.

Any help would be much appreciated.
