A highly birefringent silica microfiber was successfully developed by adiabatically tapering a low-birefringence flat fiber at a low temperature. Owing to the high fiber cross-sectional ellipticity and the large refractive index contrast between silica and the surrounding air ( δ n = 0.45 ) the flat microfiber provides an extremely high group birefringence ( B = 5.3 × 10 3 at 1550 nm). The ability to obtain high birefringence in optical microfibers offers new possibilities for polarization discrimination and control within microfiber devices, such as high-resolution optical sensors, resonators, and fiber lasers.
