Fabrication of trapezoidal-Index profile single-mode fiber
TLDR
In this article, a single-mode fiber with graded index cores was proposed as a means of producing dispersion-free singlemode fiber in the long-wavelength region near 1.3μm with relatively loose dimensional tolerances.Abstract:
Fabrication of single-mode fibers with graded- index cores was first proposed as a means of producing dispersion-free single-mode fiber In the long-wavelength region near 1.3μm with relatively loose dimensional tolerances.1 A subsequent analysis of energy confinement indicated that low loss could also be achieved with these designs.2 The first reported results on triangular profile single-mode fibers3 exhibited low loss and zero material dispersion at 7.4μm. Subsequently, triangular profile fibers were reported4,5 with zero dispersion at 1.55μm and with a loss at that wavelength of <0.28 dB/km.read more

TL;DR: In this paper, a coaxial optical fiber line is proposed and studied as a long-distance transmission medium, where the radial structure consists of a core surrounded by two clads, and the inner clads have higher refractive index than the core and the outer clads.

Characteristics of dispersion-shifted dual-shaped core fibers
TL;DR: In this article, the dispersion characteristics and bending loss of dispersion-shifted fibers with dual-shaped core and α index were investigated and it was shown that the bending loss was smaller than those of α-index fibers at a fixed condition of splicing loss.
