▎ 摘　　要

NOVELTY - The fiber has a support rod and micro-optical fiber, where the optical fiber is wound on the support rod. A support bar surface is coated with a low refractive index polymer in a uniform manner. A polymer surface is paved with uniform graphene thin film. Diameter of the micro-optical fiber is 0.5 to 5 mm USE - Micro-optical fiber for use with a three-dimensional full optical fiber polarizer, sensor and an optical element e.g. micro-resonant cavity ADVANTAGE - The fiber is simple to manufacture. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a micro-optical fiber preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a micro-optical fiber for use with a three-dimensional full optical fiber polarizer.
