Yb(3+)doped gain-guided index-antiguided fibers based on phosphate glasses are drawn using the rod-in-tube technique. These fibers have a circular core with 200 mu m diameter and a D-shaped inner cladding with a 630/480 mu m diameter for the longer/shorter axis. The negative index profile is present in these fibers, in which the core index of refraction is 0.019% lower than that of the inner cladding. Moreover, their laser amplifier characteristics are experimentally demonstrated, and the method of further improvement in laser performance is suggested. (C) 2011 Optical Society of Americ
