How do I simulate a source being a Blackbody? I am intending to have a blackbody be the incident source onto a photonic device. I want to mimic the field of a black body and the spectrum charcterstics. I am hoping to be able to change an existing source to closly resemble the black body or import the field in. Any help or advice would be welcome.

Hello, 

In Lumerical FDTD and MODE solvers, a black-body radiation source is not directly available as a built-in source type. However, my suggestion is you can approximate black-body radiation using a broadband source like a plane wave or dipole source. From my understanding, you might have to create a custom spectrum file(spectral radiance profile), you can multiply that with source's intensity. 

If you want a feature to be developed, please file it here : Ideas (lumerical.com)

Hope this helps.

Thank you.

Thanks for the response. I've seen that Zemax has the ability to create a blackbody spectrum. Do you think it is possible to convert this spectrum into a zbf file then import it into lumerical. I am currently atempting to do so but having trouble exporting the zemax file. Otherwise do you have any recomendations for creating a custom spectrum file and how that would work with multiplying that with the soruces intensity. Thanks again for the help.

Hello,

Apologies for the delayed response. I would recommend posting your question about exporting Zemax files in the Optics forum for the best guidance( Optics) 

Have you came across this example?Tech Tip Tuesday: Thermal camera simulation | Zemax Community

Also, you can get more information on creating custom source spectrum here :Creating a custom source spectrum for an FDTD source – Ansys Optics

Thanks
