Paper Abstract
A number of techniques to address fiber Bragg grating (FBG) sensors have been described in recent years. This paper discusses the use of wavelength division multiplexing (WDM) couplers to perform the detection of wavelength shifts in the optical return signals from FBG sensor elements. These components allow all-fiber versions of the wavelength filtering ratiometric demodulation scheme to be implemented. Systems based on the use of a fused WDM coupler and a planar waveguide device are described.
