Multi-plane light conversion with low plane count

CLEO/Europe, paper EJ-2, Munich, 26th June 2017
Demonstrates the principles of multi-plane light conversion (MPLC) and the design of low plane count MPLC devices for converting single-mode fibre arrays to fiber modes.

Fantastic animation and explanation. Thanks for this resource.

great presentation

How did you make those animations? They look so good!

Hi, I was wondering if you have a source code for a simulation of a MPLC composed of equally spaced phase masks?

[@joelacarpenter]

Yep, if you look in the supplemental material for our 'Laguerre-Gaussian mode sorter' paper, there's Matlab code provided...doi.org/10.14264/uql.2019.81

​@@joelacarpenter Thank you so much, the paper was really helpful, and the code is very well-documented. For context, I am a Physics undergraduate student that is trying to design a MPLC device that works with HG beams. But here I'm optimizing the patterns of the phase masks to target a certain transformation in the HG mode basis, and not to target specific N output modes given N input modes, so it's not exactly inverse design. For now, I am trying to work with 1D HG beams to later generalize it to 2D. I'd really appreciate if you could suggest any resources that I could check to learn new topics that could help me with my project.

The textbook 'Fundamentals of Photonics' has a chapter on beam optics, and a chapter on Fourier optics that's useful for getting acquainted when you're starting out in this area.
