  Hi.
  My design is attached below, In the observation line of transmission the power value which i got in the analyzer is 0.0005mW. But in my input field i have selected the power which has value of 1mW. So i am expecting 80% light extraction so should be 0.8mW. I am unable to find any error or mistake in my design please guide me with explanations.
  
  Thank you

  Jawaduddin,
  
  While I cannot comment on your expected value of 80% extraction but I can point out your boundary conditions are set incorrectly.You have your +/- Z boundary conditions set as APML which introduces loss, this should be changed to PBC (Periodic boundary conditions). It only marginally improves your extraction to 56% instead of 50%.
  
  Can you provide your reasoning for your expected value? A paper or reference perhaps?
