We have proposed the field confined holey fiber which simply consists of air holes constructed in a step index core region. As far as we know, the fiber provides the first structure to realize both large anomalous dispersions and low bend losses. The structure is useful for a practical fiber to take full advantage of the dispersion of holey fibers. The boundary element method based on a formulation in terms of transverse magnetic fields has been used to verify the characteristics of the fiber. It is shown that the proposed fiber exhibits large anomalous dispersion over +150 ps/nm/km at 1.55 μm. Compared with conventional all-silica holey fibers, the proposed fiber should have better bend losses because the fields are more concentrative in the core.
