Abstract
Embodiments of the invention relate to a single-polarization fiber that may include a W-type refractive-index profile having a depressed region along an unguided principal axis of the fiber, and a quasi step-index profile along a guided principal axis of the fiber. The quasi step-index profile may have a depressed region with a radial extent at least twice that of the depressed region along the unguided axis.
