A kind of all-glass polarization maintaining PCF is designed and fabricated using rod-in-tube method and capillary-stacking technique.The microscopic end profile of the fiber exhibits an excellent maintenance in the fine structure of the PCF.Thus,this design has effectively overcome the defect of air-holes collapse in traditional PCF fabrication process.Measurement of the fiber attenuation with the cutback method is 6.84 dB/m at 1 550 nm.The polarization measurement indicates that the fiber has a good capability to maintain polarization.Therefore it is feasible to achieve the fiber that can effectively maintain polarization and is easy to be fabricated by this all-glass design.
