Paper Abstract

The single-mode properties of LMA AS-PBGFs have been numerically analyzed. It was shown that the analysis of the losses in single-cladding fibers provides a significantly different picture of the mode confinement with respect to the overlap integral, which is commonly considered when designing active double-clad fibers. Innovative designs, based on a so-called heterostructured cladding, have been considered to enhance HOM suppression, providing a significant improvement with respect to standard AS-PBGFs.
