Less Than 0.03 dB Multicore Fiber Passive Fusion Splicing Using New Azimuthal Alignment Algorithm and 3-Electrode Arc-Discharging System

We present a novel azimuthal alignment algorithm for multicore fiber splicing that separates the core and marker information in side-view images. For two different 4-core fiber designs, average fusion splice losses of less than 0.03 dB are demonstrated using a 3-electrode arc-discharging fusion splicer.
