dc.description.abstract | We report a new method to fabricate a 4 x 1 signal combiner that comprises an output fiber port and a tapered fused bundle (TFB) with four input fiber ports. The TFB is etched in a solution of hydrofluoric acid and spliced with an output fiber of core diameter 105 mu m and cladding diameter 125 mu m. Each cladding of the four input optical fiber is etched to approximately 72.5 mu m. The etched TFB was fabricated by tapering after forming a bundle of four etched optical fibers. Subsequently, the 4 x 1 signal combiner is fabricated by fusion splicing between the fabricated TFB and output optical fiber with a numerical aperture of 0.15. The efficiency of each port of the fabricated 4 x 1 signal combiner is in the range of 93.3-98.3%. When an optical power of approximately 624.5 W was input to the signal combiner, the maximum output was similar to 612 W and the efficiency was similar to 98%. The beam quality factor, M-2 is measured to be approximately 14.6, which is calculated as the beam parameter product (BPP) of 5.02 mm.mrad.
