- The value that intensity modulator modulates the optical signal mean photon number into.
- Mean photon number: Determine by the poisson distribution formula.
- probability of having n photon with MPN:
- P(n)=(MPN^n * e^-MPN)/n!
- Is store as MPN in the fortran code.
example
@MPN_IM 0.5, 0.3
Which mean the system has two intensity modulator, and their mean photon number are 0.5 and 0.3.
