      Hi,
      I’m working on FSO channel with optical amplification based on PSK. I couldn’t get the BER for the attached circuit.

      You are using only X polarized light in your CW Laser and then splitting the polarization and using the nonexistant Y polarized light and phase modulating it.

      In the CW Laser set the Azimuth to 45 degrees in the Polarization tab.

      Regards

      Hi,
      how do u add Y polarized light ? I adjusted the azimuth angle yet no results !! I look forward for the answer

      Setting the CW laser with a azimuth of 45 degrees will create an optical signal with equal parts x and y polarized. I just noticed your polarization controller after the CW laser which is setting the polarization back to x. Check all your other components to make sure they are manipulating the polarization correctly. The optical time domain visualizer can split the signal into the separate polarizations so you can verify.

      Try BER tester!
      It links: Default/ Test sets/ Binary.
      How to use this stuff, you will find it in help topic of the component!
      Good luck!
