Nonlinear dynamics in twisted multicore fibers with PT-symmetry

Research output: Chapter in Book/Report/Conference proceedingConference contributionResearchpeer-review

Abstract

Linear and nonlinear modes of PT-symmetric multicore fibers twisted around the central axis are studied. We determine the spectral properties of such systems and show that the presence of a central core and twist can significantly change the mode structure, as well as the PT-symmetry breaking threshold. We also construct stationary nonlinear modes and investigate their stability.
