would be awesome if there were some comments throughout the code :))
just more simple to catch up

I've ported the code to C++ (using Qt for graphics): https://github.com/VioletGiraffe/Light-Simulation-cpp
Performance is quite decent as it is (on the CPU, single thread), but I'll optimize a few things some more.

This got me curious and I wondered if it's possible to converge to a steady state solution rather than a time-dependent solution.

In theory for monochromatic light it should be possible possible to represent oscillation at every point of the scene with just its complex amplitude (so amplitude + phase) and nothing else.

I wrote a quick test to see what the steady state solution looks like:

My approach is not grid-based, so I'm not sure if it's relevant to discuss it in a context of cellular automata, but I still think it is certainly relevant to try and find a steady state solution for your approach too because the process of waves actually propagating is not really needed for the final image.
