Abstract :
In this paper, we proposed a easy and stable way to selectively excite mode group in graded-index multimode fibers(GI-MMF). It was experimentally achieved by the welding of a single-mode fiber(SMF) and a GI-MMF with core/cladding diameter of 105/125 μm and adjusting the radial offset of the two fiber axis. The experiment result was discussed by observing the near-field pattern at the output of the GI-MMF. The effect of fiber length and bending curvature was also discussed.
