similarly, set the parameter of demux side

in wdm system change the parameter of different channel frequency…the frequency must be same as you have taken your input channel frequency..like 193.1 to 193.4 THz.then only you can get your result perfectly…

1)chriped signal means the signal whose frequency changes w.r.t. time, it may be increase the frequency or decrease the frequency.
2)on your attatched image the amplitude of the signal changs is quitely visible, but frequency changes a little, you can see the time axis after 100p,200p,300p.try to change the frequency more.

but in optisystem 7 one can not change the maximum and minimum amplitude value.in higher version of optisystem both maximum and minimum amplitude you can change @ Nurul, so don’t get confused.

you add your complete simulation model, then only the exact cause can be found by some one..one thing I suggest here that you can change the extinction ratio parameter of your modulator to get the good result.
