“…This is achieved by an appropriate mismatch between the EMA of the LP01 mode on either side of the splice point (z=0). This is in contrast with established belief that splice optimization requires EMA matching [1], [3], [4] and, to the best of our knowledge, it is reported for the first time.…”

“…) and the optimum conditions can be identified simply by monitoring and minimizing the transmission power loss [1], [3], [4]. In doped fibers, thermally-induced dopant diffusion plays a critical role in defining the resultant MFDs and should be considered in deriving successful splicing techniques [3], [4]. The situation becomes more complicated when SM fibers are spliced to multimode (MM) doped fibers, which is usually the case of highpower lasers and amplifiers.…”

In this work, we optimize singlemode-to-multimode doped fiber splices by varying the arc duration and monitoring HOM excitation, using the standard S 2 technique. By measuring the diffused refractive index profile (RIP) distributions around the splice point, contrary to current belief, we show that the optimum arc duration does not corresponds to RIP that match the MFDs on either side of the splice point. Furthermore, we show that the MM doped fiber diffused RIP is longitudinally non-adiabatic and results in additional power transfer from the excited FM (LP01) to HOMs (LP02). As a result, we find that the optimum arc duration corresponds to a substantial MFD mismatch which results in an initial excitation of the HOM (LP02) with the appropriate magnitude and relative phase to nullify the corresponding HOM power generated in the non-adiabatic region.

A non-interferometric imaging technique in conjunction with Abel inversion is used to directly and quantitatively examine the changes in optical fibers due to the heating produced during arc-fusion splicing as a function of fusion arc parameters. Phase images in the vicinity of a fusion splice are obtained using Quantitative Phase Microscopy, allowing the refractive-index change to be reconstructed with high spatial resolution. This simple, nondestructive method confirms that, for a fixed arc current, while the fusion time increases, the refractive-index of both fiber cores within the fusion region decreases in magnitude, the core region broadens, and the axial gradient decreases.
