Twisted clad microstructured optical fibers: revisited

Applied Physics B, 2014
The paper discusses confinements corresponding to low-order sustained hybrid modes in twisted clad microstructured optical fiber with twists in the form of conducting sheath helix structure introduced at the core–clad interface and inclined at certain angles.

Leaky modes in twisted microstructured optical fibers

Waves in Random and Complex Media, 2007
The purpose of this paper is to investigate the effect of a twist on the losses of leaky modes in microstructured optical fibers (MOF). A helicoidal system of coordinates is introduced to define the structure and to set up the problem. These coordinates, albeit non-orthogonal, preserve the translational invariance in a way that allows a two-dimensional

The effect of coupling between core and cladding modes in twisted microstructured optical fibers

Micro-Structured and Specialty Optical Fibres V, 2018
We provide a detailed explanation of the effect of coupling in helical microstructured optical fibers (MOFs) based on decomposition of core and cladding modes into multiple angular harmonics, each carrying integer orbital angular momentum and spin. The obtained results show that in twisted hexagonal MOFs, the fundamental mode characterized by spin σ ...

Finite element modeling of microstructured optical fibers: leaky modes, twisted geometries, and spatial Kerr solitons

SPIE Proceedings, 2008
Microstructured optical fibers have much more degrees of freedom concerning the geometries and index contrasts than step-index fibers. This richness opens totally new fields of application for fiber optics. The finite element method appears as an extremely versatile tool to compute the propagation modes in such systems as it allows to take into account
