Based on mode field coupling theory, a model to calculate the butt-joint coupling efficiency between a multi-mode fiber and a single-mode fiber is presented.
The coupling between butt fiber and cone lensed fiber is described in this paper. A theoretical model is presented and the formula of coupling efficiency is given.
