| Resumo | |
We study the application of a tubular-lattice hollow-core fiber displaying thin cladding tubes as a high-sensitivity and large-dynamic range curvature sensor. The device working principle is based on bending-induced core and cladding modes couplings occurring at specific wavelengths and at specific curvature radii. Our characterizations allowed us to determine a sensitivity of (29.3 +/- 0.4) nm/m(-1) for a curvature variation range of 17 m(-1). These figures are high when compared with other curvature sensors based on different optical fiber-based sensing configurations. We understand that our work provides a valid path for achieving new hollow-core curvature sensors with enhanced sensitivity and large dynamic range. (AU) | |
