A novel in-fiber integrated 1×2 coupler has been proposed and demonstrated. By way of splicing and tapering at the fusion point of one-core single mode fiber and the two-core single mode fiber, an effective coupling technique is implemented. The coupling processing is simulated by the beam propagation method. The effects of the two-core fiber non-symmetry and the refractive index of each core of the two-core fiber slightly deferent is also investigated and discussed.
