Abstract
Photonic crystal fiber designs for power scaling of single-polarization amplifiers are presented. These fibers incorporate a core with a refractive index slightly lower than that of pure silica and borosilicate stress rods embedded within the photonic crystal lattice. They are realizable as rod-type as well as conventional photonic crystal fibers. The core index change results in a fundamental mode profile that is flattened relative to that of standard photonic crystal fibers. A continuum of mode profiles ranging from approximately Gaussian to approximately top-hat can be achieved in this manner. The optimal parameters of these designs depend on the desired coiling radius, birefringence, and mode area. Preliminary experimental results are presented.
