Method of angle fusion splicing silica fiber with low-temperature non-silica fiber
A low-cost approach is provided for forming a low splice loss, low back reflection loss and mechanically robust angle-fusion splice between a standard silica fiber and a low-temperature non-silica glass fiber. This is accomplished by angle cleaving the silica fiber, square cleaving the non-silica fiber and then asymmetrically heating the fibers to form an angle fusion splice. A matched angle at the end of the non-silica fiber is generated in situ during the splicing process. The tip of the angle-cleaved silica fiber may be polished flat back to the edge of the core to reduce the range of motion of the non-silica fiber during splicing thereby further reducing splice loss and enhancing the mechanical strength of the joint.
