| Abstract: | This paper proposes a method using non-equilibrium Mach-Zehnder interferometer composed of a 2×2 coupler and a 3×3 coupler as wavelength demodulation for fiber grating, by using the principal of interference measurement about the signal light. The theoretical studies are carried out exhaustively and the whole experimental system is constructed. The experiments show the system has the measurement resolution of 1pm and the precision is less than 3pm. |
