It was shown that the aspect ratio of the hollow core can be controlled by tuning the negative pressure in the space between the intermediate preform cane and outer jacketing tube, and by placing this preform assembly off-center in the furnace, resulting in lateral tension during the final draw. Modal birefringences of fabricated PBGFs with different aspect ratio were measured using a Sagnac loop interferometer . For the elliptical hollow core PBGF with aspect ratio of 2.34, the modal birefringence was measured to be about 4.6 ｘ10 -2 at 1,550nm. 2008 Optical Society of America OCIS codes: (060.2280) Fiber design and fabrication; (060.2400) Fiber properties; (120.5790) Sagnac effect.
