| titleOfInvention | Single crystal glass composite optical fiber |
| abstract | A single crystal glass composite optical fiber. The composite optical fiber is produced by using a single crystal strip, which is produced by single crystal glue-free bonding and mechanical grinding and polishing, as a core and using multi-component oxide glass as a cladding, and the diameter of the end face of the core is as low as tens of microns. The utility model discloses the advantage: as the cladding material adopts a plurality of oxide glasses with different components, the composition of the oxide glasses can be adjusted in a wider range, so that the numerical aperture between the fiber core and the cladding in the single crystal glass composite optical fiber, the expansion coefficient of the oxide glasses and other physical and chemical properties can be adjusted in a larger range. The technical bottleneck that the polished micro-sized single crystals are difficult to insert into the micro-sized glass pores without gaps is also solved by adopting a relatively simple chemical coating technology. Along with the adjustment of the composition, the cladding can also generate chemical durability, so that the single crystal glass composite optical fiber can effectively resist the corrosion of the external environment. |
