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 (Lφ ), transverse offset (Ld), and axial tilt (Lθ), as well as some of their combinations, are calculated under typical parameter range. Linear combination of L φ and Ld may cause considerable error, while Lφ could be considered as independent from Lθ with fairly good accuracy. Comparisons with previous works reveal some errors in the latter case
