How to make aplitude of all harmonics same

(joined June 2015)

Participant

I am generating a multi-wavelength source using fiber non linearity and phenomenon of SPM(Self Phase Modulation) My project is working very fine and out put is satisfactory but the amplitude of different harmonics generated is not same. Is there any way to make the aplitude(Power) of all harmonic components same so that I can use them further for WDM? Kindly Help!!!
Out put snap shot is attached.

Thanks in anticipation.

Dear Ahmad,
If you are not committed to non-linearity you can make a flat comb using MZM

    Sorry aadilqau,
    I use the last version. However, you can use the attached snapshots to design in your own software.
    I hope this help you.

    You get a perfect comb. You can decrease the line width of the laser to show a clean image. However your results is perfect.

Respected Sir,
The circuit you provided is working very fine but the output of the WDM DeMux is not as the Wave is at the output of the modulator. Please Help in this regard. Thanks in anticipation.

Use Optical spectrum analyzer to show the output.

to my knowledge, There is no device for pulse picker in Optisystem.
you can use MZM for that purpose.
check the attached paper.

  Hi Dismas,
  
  As far as I know, OptiSystem is the software to simulate optical systems and has a system approach. It is not somehow that much concerned with the physical processes (even though the components are models of real physical ones) so as to be used in order to show these concepts. If you want to use a light source, you can go to the transmitters library and show the available components there.
