Abstract

A highly biréfringent silica microfiber was successfully developed by adiabatically tapering a lowbirefringence 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 (δn = 0.45) the fiat microfiber provides an extremely high group birefringence (B = 5.3 X 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.
