We report the first fabrication of polarization rocking filters in a highly birefringent elliptical microfiber. The rocking filters are 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 is achieved at a resonant wavelength of ~1556.4 nm with a device length of ~3.12 mm. High-order polarization rocking filter was used to measure the refractive index with sensitivity of 32036 nm/RIU.
