We have developed a novel type of holey fiber which has a conventional raised-index core surrounded by two layers of air holes with different sizes. The fiber has single-mode operation and shows a low bending loss even for an extremely small bending diameter and a low splicing loss for fusion splicing to a conventional single-mode fiber. The structure and the properties of the fiber are reported in this paper.
