Abstract :
A curvature fiber optic sensor using a Two-Core fiber is demonstrated. The sensor spectral response shifts as the fiber is bent while the intensity peaks remain practically unaltered. The proposed sensor exhibits linear response and a sensitivity of -137.8763 nm/m-1 for curvature ranging from 0 m-1 to 0.27 m-1, which makes it suitable to measure small curvatures with high sensitivity.
