A semicircular fiber (SCF) was fabricated by flame-heated treatment for displacement sensing application. By launching a laser beam into the SCF, interference was created at the output port of the structure due to fiber-bending-induced birefringence. Experiments indicate that the resonant wavelength was shifted to shorter wavelengths with increasing transverse displacement. Displacement sensitivity increases with the decrease of the bending radius of the SCF. A high sensitivity of 1100nm/mm was obtained for the SCF with a bending radius of 0.57 mm.
