How to simulate and optimize chips with multiple light sources at the same time？

[ROSSI-49]

When using LumOpt for simulation optimization, I noticed that when setting the optimizer, only one 'source name' can be set. So, if I want to input two different light sources at the same time in the script, how can I do it?

I have the same issue when using lumopt to design directional couplers. I appreciate the help!

Luckily, I've found a possible workaround.In the document "optimization.py",we use Init() to initialize the optimizer，in it the code provide an available extension parameter calld "source_name".
Following the use of this variable in the function and adding the parameter interface provided by the function, you can initialize multiple light sources.

Thanks, I am looking for a way to design a 2X2 DC, it seems that the design tool for each simulation completely ignores the other output. Do you have any suggestions for this?

Many Thanks

I am also trying to do something similar, did you end up having any success?

can you tell me more details about how to "adding the parameter interface"? if you can update your source codes to your github,i will be very very very appreciate
