Splice loss between different Gaussian-elliptic-field single-mode fibers

Splice losses between two different Gaussian-elliptic-field single-mode fibers are derived under various mechanical misalignment conditions. Loss values for azimuthal rotation (L/sub phi /), transverse offset (L/sub d/), and axial tilt (L/sub theta /), as well as some of their combinations, are calculated under typical parameter range. Linear combination of L/sub phi / and L/sub d/ may cause considerable error, while L/sub phi / could be considered as independent from L/sub theta / with fairly good accuracy. Comparisons with previous works reveal some errors in the latter case.<
