Abstract

In this letter, we report bending and strain sensitivities of helicoidal long-period fiber gratings fabricated by twisting single-mode fibers during CO₂ laser irradiation. Linear spectral shifts of the resonant wavelengths under the bending and tensile strain were observed with the sensitivities of 11.7 nm/m^-1 and 1.1 pm/μ ε, respectively. The corresponding transmission power variations at the resonance wavelength were 4.1/m^-1 and 2.2 × 10^-4dB/με, respectively. Detailed measurement techniques and sensor applications are discussed.
