Phase Shifted FBG is to introduce phase discontinuity points in the FBG, and generate a very narrow transmission window in the reflection spectrum of the FBG, the transmission wavelength varies with the phase shift amount. Phase Shifted FBG can be used as a demultiplexer in dense wavelength division multiplexing (DWDM) systems. The size, location and points of phase shift have an important impact on the performance of the demultiplexer.
