Abstract

We report on sensing characteristics of a long period grating fabricated in polymer microstructured fiber using transverse periodic loading combined with fiber heating. The grating is characterized for strain and hydrostatic pressure sensitivity and shows linear response to both parameters with sensitivity coefficients equal, respectively, -1.39 nm/mstrain and 2.29 nm/MPa. We also measure the variation of the resonance depth induced by both parameters and study the temperature response of the grating.
