本文提出了一种简单有效的方法，通过绝热锥形熔接到单模光纤来选择性地激发多模光纤的基模。我们通过实验证明了该方法在单模和多模光纤之间绝热变径拼接（变径腰=15微米，均匀长度=40毫米），并表明它提供了成功的模式转换/连接，并允许在多模光纤中几乎完美的基模激发。获得了优异的光束质量（M(2)约为1.08），具有低损耗和高环境稳定性。
We propose a simple and effective method to selectively excite the fundamental mode of a multimode fiber by adiabatically tapering a fusion splice to a single-mode fiber. We experimentally demonstrate the method by adiabatically tapering splice (taper waist=15 microm, uniform length=40 mm) between single-mode and multimode fiber and show that it provides a successful mode conversion/connection and allows for almost perfect fundamental mode excitation in the multimode fiber. Excellent beam quality (M(2) approximately 1.08) was achieved with low loss and high environmental stability.
