NUBM08 Array - sources for knife edge reflectors, fiber coupling strategies?

I would love to see it work, I wonder what you would get out of the other end of the fiber and if any power loss will occur?

It talks of multiplexing in the video, sometimes the way the wave fronts are combined prevent power loss.

Thinking more about multiplexing lasers.
What are all the methods?
