title: Structural polarization-rocking filters in highly birefringent microfibers.
abstract: We report the first fabrication, to our knowledge, of polarization-rocking filters in highly birefringent elliptical microfibers. A rocking filter was made by periodically heating/twisting a microfiber with an ellipticity of ∼0.7 and a diameter of ∼2.8  μm along its major axis. Strong input polarization suppression of ∼20  dB was achieved at a resonant wavelength of ∼1556.4  nm with a device length of ∼3  mm.
