…then we just published the right technique for you. We used a multi-plane light conversion technique to convert a complex light field coming out of multi-mode fiber into a Gaussian structure and coupled it into a single-mode fiber. And this with super high efficiency!

Congrats to all co-authors and in particular Oussama for making this nice work happening!
