We demonstrate a Yb-doped hybrid fiber with anomalous dispersion in the 1 μm spectral range, where asymptotically single-mode behavior is achieved with a differential mode amplification technique.The fiber has a dispersion of 70-100 ps/(nm·km) in the spectral range from 1.020 μm to 1.055 μm and a sharp dispersion peak (a
