Title:
BUNDLED OPTICAL FIBER
Document Type and Number:
WIPO Patent Application WO/2024/084562
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a bundled optical fiber capable of transmitting light even if power deviation occurs at a bundled portion and outputting desired power from where the bundle is
split into a plurality of radiation units. A bundled optical fiber 36 according to the present invention bundles a plurality of single-core optical fibers 51a, and is characterized in that the coupling ratios for coupling light from the outside to the single-core optical fibers 51a at one end thereof differ between at least a part of the single-core optical fibers 51a and the other single-core optical fibers 51a. In the bundled optical fiber 36, the coupling ratios are varied by changing the number of apertures or diameter of the cores 52 of the single-core optical fibers 51a.
