Hi
I am using Optisystem7,
When i Modulate White light source using Simple MZM-Push pull technique , no side bands found.
White light source power=-100dBm (Frequency is 1542nm /194.4.THZ)
Sin Generator (Radio Frequency)= 25GHZ.

As per theoretically side bands should be formed of noisy signal but here i cannot found such side bands.
Can you please suggest me the reason behind this scenario?

Thanks in advance

      I’ve checked the paper quickly, you suppose to build a MZI not MZM. Please refer to figure 7 it shows the block diagram.
      All components are in OptiSystem and you should be able to simulate it in OptiSystem. You need to couplers and delay elements.
      Once you design the project, please send me the layout as a zip file to review it.
      Regards,
      Ahmad
