Cutoff Mechanisms in Bend-Insensitive Single-Mode Fibers
Fibers single-mode Fiber properties
2015/5/22
We present a comprehensive study that explains the specific mechanisms that govern the cutoff behaviors of G.657 single-trench-assisted Bend-Insensitive Single Mode Fibers (BI-SMFs) compared to those ...
Multi-Path Interference in a bend-insensitive fiber
Multi-Path Interference bend-insensitive fiber
2015/5/20
Multi Path Interference noise in a bend-insensitive fiber is examined by wavelength and polarization scanning, by sample stretching, and by increasing the end splices misalignment,to find the splice l...
New designs of bend-insensitive multimode fibers are proposed. The bending loss can be reduced by a factor of 10 while meeting all other standard requirements. The design concept is validated by actua...

Investigating Micro-Bend Sensitivity Large-Mode-Area Bragg Fiber
2015/7/14
Phase-sensitive Optical Low Coherence Reflectometry technique is used to characterize the modes couplings induced by micro-bends in a Large-Mode-Area Bragg fiber made with PCVD. Single-point and multi...
Solid low-bend-loss transmission fibers using resonant suppression of higher-order modes
transmission fibers resonant suppression higher-order modes
2015/7/30
Ring-assisted fibers suppress unwanted modes, improving the tradeoff that limits bend loss. Fabricated fibers achieve low bend loss and compatibility with standard fibers required for fiber to the hom...
Bend-Induced Transformation of the Transmission window of a Large-Mode-Area Bragg Fibre
Transmission window Large-Mode-Area Bragg Fibre
2015/7/30
We study the effect of bends on the transmission window of the first PCVD large-mode-area Bragg fibre. The origin and the consequences of this effect are also presented.
