Abstract

A new method of decreasing connecting loss between Er3+-doped fiber(EDF)and single mode fiber(SMF) is presented in this Paper. The low connecting loss has been obtained by tapering Er3+-doped fiber, which makes the transmission mode of Er3+-doped fiber expand so that it matches the transmission mode of single mode fiber Perfectly. The connecting loss less than 1 dB has been obtained with this method in the experiment.
