      hello!
      How to Implement Carrier-Suppression Single Sideband Modulation (CS-SSB) with dual parallel Mach-Zehnder modulator (DP-MZM) in optisystem?

      I have built the model, but the result does not implement carrier suppression. What’s wrong with my parameters?
      The circuit diagram is attached. The parameters are as follows.
      The upper and lower sub-MZM bias voltages are V1=2,V2=0, and the right MZM bias voltage is V1=2,V2=0.

      Dear Hu,
      you need to set properly the applied voltages to the modulators to suppress the carrier as shown in the attached image. Please refer to the example (ROF_carrier suppression.osd) in OptiSystem Example library for guidance.

      Ahmad
