@DELAY PERIOD NUM

• Used when @DELAY_PERIOD_SW is .true.. Set the difference of long path and short path passing time in Mach-Zehnder Interferometer is @DELAY_PERIOD_NUM * @PULSE_PERIOD.
• Is store as delay_period_num in the fortran code.

example

@DELAY_PERIOD_NUM
1

Which mean the difference of long path and short path passing time in Mach-Zehnder Interferometer is one pulse.
