A fusion scheme is proposed for achieving low-loss splice between photonic crystal fiber (PCF) and single-mode fiber(SMF) using conventional arc fusion splicer. Experimental measurements and theoritical calculations are both involved in this sheme. Firstly, how PCF′s air-hole structures varied along with the applied fusion power was observed by changing fusion parameters, such as fusion time and current. Then the mode distributions at the fiber tips and the corresponding splice loss between the two fibers were calculated, and the fusion power range for low splice loss was thus deduced. In return, the optimal sets of fusion splice parameters were determined and low-loss high-strength splicing between the PCF and SMF was achieved. The uncertainties, like the extent of hole contraction of the PCF and its effect on the matching between the two fibers are cleared up in this sheme. Also, the fusion efficiency and quality are both improved owing to the scheme′s effectivity in determining an optimized set of fusion parameters for splicing PCF to SMF.
