Fabrication of All-glass Polarization Maintaining Photonic Crystal Fiber

Abstract: A kind of all-glass polarization maintaining PCF was designed and fabricated using rod-in-tube method and capillary-stacking technique. The end profile of the fiber was observed through a microscope. The result showed that the microstructure of the PCF kept well. So, this design effectively overcame the difficulty of air-holes collapse in traditional PCF fabrication process. Fiber attenuation was measured as 6.84dB/m at 1550 nm by the cutback method. The polarization measurement indicated that the fiber had a good ability of polarization-maintaining. Therefore it is feasible for getting the fiber, which has effective polarization-maintaining ability and easy to fabricate, by this all-glass design.
