Integrated orbital angular momentum mode sorters on vortex fibers

S Lightman, I Bleyhman, L Somers, G Hurvitz… - Optics Letters, 2022 - opg.optica.org
We design, fabricate, and characterize integrated mode sorters for multimode fibers that
guide well-separated vortex modes. We use 3D direct laser printing to print a collimator and …
