We report the fabrication of what are believed to be the first microstructured optical fibers
with uniformly oriented elliptical holes. A high degree of hole ellipticity is achieved with a
simple technique that relies on hole deformation during fiber draw. Both form and stress-
optic birefringence are characterized over a broad wavelength range. These measurements
are in excellent agreement with numerical modeling and demonstrate a birefringence as
high as 1.0× 10^-4 at a wavelength of 850 nm.
