摘要

We present the fabrication and characterization of a microstructured fiber with ultrahigh birefringence. The fiber, consisting on a small elliptical core suspended from thin silica bridges, has been fabricated adapting the stack and draw method for microstructured fibers to the well known fabrication procedure for conventional elliptical core optical fibers. The ellipticity of the core and the air-hole array has been achieved by controlling the lateral tension between the preform and the jacketing tube. The group index birefringence has been measured using a frequency-domain modulated carrier method and a modal interferometer method. Both methods proved appropriate and showed consistent results. A group index birefringence higher than 7 x 10~(-3) is demonstrated, being this value higher than those reported to date.
