Abstract

We report the fabrication of long-period gratings (LPGs) in highly birefringent (Hi-Bi) microfibers. The LPGs were fabricated by using a femtosecond infrared laser to modify the surface or a CO2 laser to induce micro-tapers periodically along the Hi-Bi microfibers. These LPGs have pitches from tens to hundreds of micrometers and very strong polarization dependent resonances. A LPG fabricated on a Hi-Bi microfiber with a major-diameter of ∼2.8 μm and an ellipticity of ∼0.7 demonstrated a refractive index sensitivity of ∼4623 nm/RIU in water.
