  Hi Garima,
  
  It seems you have not attached your reference paper. And you have not mentioned the exact problem with random number generation. In the meanwhile, if you want the output of the subtractor to be zero, you need to disable “generate random seed” for both PIN photodetectors in their properties.

  Hello Garima,
  
  In your system, the output of Electrical Subtractor to Oscilloscope visualizer is ‘0’. You have only noise at the output.
  From the CW laser, I saw the output signal using OTVD gives 10e^6 signal. When you split the signal and sending it to photo detector,you got the two 5e^6 as output with some noise. Finally you used the subtractor, so you got the ‘0’ as signal output with some noise. Till this, your system is working. But What output are you expecting?
