Abstract

We fabricate and demonstrate a long-period grating (LPG) by periodically tapering a section of standard single-mode fiber using resistive filament heating. The obtained LPG has a large peak transmission attenuation of-30.31 dB with only 22 periods in a 1.0-cm long optical fiber. Such a LPG exhibits unique characteristics for sensing applications. The bending and strain sensitivities are 1.74 nm m and 1.11 pm/με, respectively. The polarization dependent loss is large, up to 11.65dB, caused by asymmetric index profile in the cross section of the tapered LPG.
