"Zero power" does not include the power needed to translate information between electronic and optical domains and the light source itself.

Yes, correct. I will phrase this better in the future. The zero-power refers only to what is, in effect, the optical replacement for the ocean of matmul you have in standard Transformer implementation.

I apologize for not being clearer.

The goal isn't actually "zero power" - the goal is "so little heat dissipation in orbit is easy".
