SILICA-BASED SINGLE CORE OPTICAL FIBER, SILICA-BASED MULTI CORE OPTICAL FIBER, AND FABRICATION METHOD FOR THE SAME |
摘要 |
A silica-based multi core optical fiber and a fabrication method for the same are provided, and include two or more cores of GeO2-SiO2 glass including an fluorine concentration not less than about 15 w % and a germanium concentration about 0.05 wt % to 2 wt %, in a core. A relative refractive index difference of a cladding and a core is not less than about 3%; and a ratio of a cladding diameter to a core diameter is about 1.02 to 3.0. A silica-based single core optical fiber is also provided, and includes a core having a germanium concentration not less than about 15 wt % and an fluorine concentration about 0.05 wt % to 2 wt %. |
