Light petal generation structure for optical fibers

Abstract

A light petal generation structure for optical fibers, especially applied to a decorative optical fiber, collects loss light at a nodule position, and directly transforms into an enlarged and bright light petal. The structure uses primarily an optical fiber with side losses, wherein light-dot generation grooves are opened at a cladding layer on an exterior circular surface at nodule positions. A reflection mirror facing a direction of incident light is emplaced in the generation grooves. A loss light is directly reflected by the reflection mirror, and enlarged through a curvature of a core of the optical fiber, thereby transforming into an enlarged and bright light petal on an exterior circular surface at the other side of a spun of optical fiber.
