      When simulating QPSK, I chose cascaded MZM to generate QPSK signal. Can I choose to demodulate by MZDI at the receiving end? I don’t see a simulation in the example, so it’s a little unclear. thank you.

      Dear Sun,
      Typically, delayed interferometers are used in DPSK. I am not sure if the MZDI would work for QPSK. However, my guess the operation depends on the applied delay in both arms of the coherent detectors if it would work. You may email me your project as zip file to check it. My email is ahmad.atieh@optiwave.com.
      Regards,
      Ahmad
