Point source modeling in non-sequential mode

Hi there Zemax community, 

I have some far-field information (Ex,Ey,Ez, Hx, Hy,Hz) for a point emitter which I have extracted from a FDTD simulation. I would like to now use these components in order to generate a source model for my FDTD point source using Zemax in non-sequential mode. 

As far as I understand it, I should use the Poynting flux instead of the field components for describing my source profile within Zemax right? 

Also, I could use some rope in finding some reference on how to use the extracted far-field information (which can be given in spherical coordinates) to set a distribution of rays, which represent the far-field energy flux for my FDTD source in non-sequential mode.

Any comments and help will be appreciated!

Hi CJ,

 

You can reference this Lumerical article for extracting ray data in-general:

https://optics.ansys.com/hc/en-us/articles/360034416754-Export-to-ray-tracer

 

 

Regarding Formatting for Zemax OpticStudio:

A script already exists to reformat far-field distribution data for Zemax OpticStudio, from Lumerical! Here is an example where the script can be downloaded from:

https://optics.ansys.com/hc/en-us/articles/360042715273-Planar-OLED-ZEMAX-Interoperabillity

(The Patterned OLED example also contains the script.)

 

 

Best Regards,
