Ytterbium-doped polarization-maintaining fiber in a pedestal geometry is demonstrated using MCVD and a novel in-situ doping technique. The aluminosilicate pedestal layers minimize the thermal expansion mismatch against the silica outer cladding and permits complete freedom of location for the stress-applying parts in the fiber. A birefringence of 2.4×10-4 is experimentally determined. The fiber delivers linearly polarized laser exhibiting 79% slope efficiency with a polarization extinction ratio of 12 dB.
