Optical transmission modulation by fiber guide bending

Abstract

Abstract The study is aimed at finding out the influence of bending on the waveguide from the point of view of ray equivalence with its modification based on the concept of local plane waves to provide an illustrative way to describe optical transmission in a multimode optical fiber. The paper covers the physical principles of modulation of optical transmission of fiber light guide by the bending radial variation. In addition, the authors obtained the expression for the total radiant energy in the light guide bend section/cutting in the ray equivalence. The mechanism of modulation of the fiber optical light guide and obtained mathematical expressions are the theoretical foundation for producing amplitude fiber-optic sensors.
