Abstract

We propose and demonstrate a Sagnac loop interferometer composed of a novel Hi-Bi photonic crystal fiber with two large air holes in the outer cladding region as a curvature sensor. It has been shown that it has an insensitivity to temperature and a curvature sensitivity of 0.519 nm/m^-1 when the fiber is bent in the slow axis.
