Linearly polarized orbital angular momentum mode purity measurement in optical fibers.
TL;DR: The proposed method for measuring the mode purity of linearly polarized orbital angular momentum (OAM) modes in optical fibers is validated and it is experimentally demonstrated in a two-mode fiber.
Journal ArticleDOI
Core-cladding mode coupling of tilted long period fiber gratings in dual-mode fibers
TL;DR: In this paper, the authors present a theoretical study on the mode coupling between core modes and cladding modes of the tilted long period fiber grating (TLPFG) in dual-mode fiber.
