We demonstrate an Yb-doped polarizing all-solid photonic bandgap fiber for single-polarization and single-mode operation with an effective mode area of 1150m2, a record for all-solid photonic bandgap fibers. The differential polarization mode loss is measured to be 5dBm over the entire transmission band with a 160nm bandwidth and 15dBm on the short wavelength edge of the band. A 2.6m long fiber was tested in a laser configuration producing a linearly polarized laser output with a PER value of 21dB without any polarizer, the highest for any fiber lasers based on polarizing fibers.
