Abstract

The properties of a large mode area Yb-doped double-cladding hybrid photonic crystal fiber, with antisymmetric high-index inclusions, have been analyzed. Simulations, carried out through a finite-element based modal solver, and experimental measurements have demonstrated the narrow spectral filtering capability of this fiber, with a passband of about 80 nm in the Yb gain region. Moreover, high-order mode suppression has been demonstrated with a proper air-hole size. Finally, the stress-induced birefringence due to the Ge-doped rods used as high-index insets has been investigated, accounting for the polarization-maintaining behaviour of the manufactured fiber.
