  Dear Staff Member at Lumerical,
  Could you give me some recommendations on what type of source I could use to model the transmission of an omnidirectional LED source, thank you.
  Best wishes

  If your LED is layered, thin-file type, I would suggest to use stackdipole:
  stackdipole - Script command
  FDTD vs stackdipole - halfspace emission in a multilayer stack
  Usually it uses dipole source for simulation, and average the results with 2 or 3 dipole sources separately, depending on if the LED has symmetry.
  Please refer to this example Micro-LED
