Techniques and systems suitable for performing low-loss fusion splicing of optical waveguide sections are provided. According to some embodiments, multiple laser beams (from one or more laser) may be utilized to uniformly heat a splice region including portions of the optical waveguide sections to be spliced, which may have different cross-sectional dimensions. According to some embodiments, the relative distance of the optical waveguide sections and/or the power of the multiple laser beams may be varied during splicing operations.

Large diameter optical waveguide splice

Low-loss large diameter optical waveguide attachment devices (i.e., pigtails) and methods and systems of making the same are provided. The optical waveguide attachment devices may include an optical fiber (or other type waveguide) embedded in a larger diameter carrier tube. According to some embodiments, multiple laser beams (from one or more laser) may be utilized to uniformly heat the circumference of the carrier tube. According to some embodiments a maria may be formed in one end of the capillary tube to facilitate optical waveguide insertion and/or provide strain relief.
