TLDR
In this paper, the dependence of the transmission of light on the bending radius of a waveguide from the point of view of mode-ray equivalence was analyzed and the influence of directional properties of a radiation source and the parameters of the waveguide itself on the sensitivity to bending was analyzed.Abstract:
An analysis is made of the dependence of the transmission of light on the bending radius of a waveguide from the point of view of mode–ray equivalence. A study is made of the influence of directional properties of a radiation source exciting a waveguide and of the parameters of the waveguide itself on the sensitivity to bending. The dependences of light transmission on the bending radius are derived for various waveguides and angular distributions of the radiation emitted by a source.read more

Accurate characterization of the transmittivity of large-diameter multimode optical fibers
TL;DR: Good agreement is obtained between calculated variations and experimental results for the three kinds of fiber tested, and this method is a good means to evaluate separately the various processes contributing to the attenuation of open beams along the fibers and to determine which process should be worked on to improve the transmittance.
