Fast mode decomposition in few-mode fibers [PDF]

open access: yesNature Communications, 2020
Characterizing the modes at the output of a multimode fiber is time consuming due to computational cost. Here the authors present an algorithm for few-mode-fiber mode decomposition with a fast processing time and using only intensity measurements.

Forward Brillouin scattering in few-mode fibers [PDF]

open access: yesLight: Science & Applications
Forward Brillouin scattering is an opto-mechanical effect in which two co-propagating optical fields couple with an acoustic mode in a common medium. The effect has been studied in standard optical fibers since 1985, however nearly all studies have been ...
