How to mimic photo-luminescence measurement using FDTD simulations?

I am trying to mimic PL measurement using FDTD simulations. I am using the bunch of dipole sources as the emitters. It would be really helpful if you can suggest me to calculate the PL intensity using DFT monitor.

    Hi @Varsha,

    Thank you for posting your question. Typically, you can use far field projection from a DFT monitor to get the emission pattern that would be measured. I don't think you necessarily need to use a dipole cloud, 1 dipole could be enough. Note if the PL is isotropic, you need 3 simulations (1 for each dipole orientation) and average the far field intensities (abs(E)^2) to get the correct emission. A similar methodology is used for OLED simulations.

    I hope this will help.
