LED Light source




How can we insert a light source which behaves like an LED in FDTD solutions. In other words, is it possible to create an LED light source with a certain viewing angle and luminous intensity incident on a test structure in the FDTD solutions and study the interaction of the LED light with a particular structure.




If I am not mistaken, there are no in-built LED light sources in FDTD solutions.
These are the sources available in FDTD solutions:

  1. Point source
  2. Gaussian and Cauchy/Lorentzian beam sources
  3. Plain wave source
  4. Total field scattered field source
  5. Mode source
  6. Import source
    If you go to the link below you will find a detailed explanation of all the sources mentioned above.

    You can customize your source profile using the “import source” option. If you go to this link: (https://kb.lumerical.com/en/index.html?ref_sim_obj_sources.html)
    and follow the instructions given there, you will find the methods to customize a source field.
    I hope this was helpful.
