%X The possibilities of coupling and splitting using an embedded V-groove are presented and analyzed in this paper. While the incident beam is refracted on the surface of the groove, keeping the angle a at a special value which is determined by the refractive indexes of core and cladding,efficient coupling and tunable splitting ratio can be achieved. The expression of the splitting ratio of this device is shown. The beam can be coupled into one side of the core of the fiber,but it can't be splitted into the other side through inner reflecting on the surface of the groove.
