OPTICAL FIBER MICROWIRE DEVICES AND MANUFACTURE METHOD THEREOF

摘要

Herein presents an optical fiber microwire device, wherein the device comprising a silica tube, an optical fiber (2) inserted into the silica tube (1) and pigtailed at two sides, wherein the two ends of the silica tube (1) are fused with the optical fiber (2) to form a solid structure, or the two ends of the silica tube (2) are filled with silica rods (3), silica capillaries (4) or segments of optical fibers and fused to form a solid structure. The silica tube (1) together with the optical fiber (2) inside is then tapered to form a micro structure region. Therefore, the micro structure region is consisted of the tapered optical fiber as the microstructure core, tapered silica tube, and the air in between. This invention combine the manufacture of optical fiber microwire and the sealing process, avoiding the disadvantages of the conventional tapered optical fiber microwire, such as fragile mechanical structure, and sensitive to the outer environment variations.
