      You can found AMI related examples in optisystem versions 12,13.

      i tried version 12. and i build a similar system according to the example. all is working fine until after Mach-Zehnder modulator. my signal seems to be lost after that modulator. do anyone know what happened? i uploaded my work which is AMI trial and the example which is AMI example.

      hi chee,
      The reason is due to modulator settings.After modulator, time domain visualizer is showing constant line.So voltage settings of Mach Zehnder modulator has to be adjusted.

      Put the setting as given “AMI-example”,you will get output.
