The low-loss splicing technique between photonic crystal fibers (PCF) and normal single-mode fibers (SMF) is a critical problem that should be solved before the application of PCF. A new method to realize low loss splicing based on the new technique of mode field matching by fusion taper rig is proposed. The preprocessing that changes the mode-field diameter (MFD) is first done by fusion taper rig. Using traditional arc-fusion method combined with fusion taper rig, the experimental study on splicing loss between different PCF and SMF is performed. During the experiment, mode field matching between different PCF and SMF is observed by changing fusion taper rig′s parameters. The splicing loss can drop to below 0.3 dB by optimizing the discharge parameters, and then satisfy the application requirement. In return, the optimal sets of fusion splice parameters are determined and low-loss, high-strength splicing between the PCF and SMF is achieved. This method can provide the reference for other similar splicing between PCF and SMF.
