Features
Phase shifted FBGs have a very narrow peak within its transmission/reflection spectrum. Phase shifted FBG is a grating with phase defect in the center. While the grating length determines its bandwidth, spectral width of that peak depends on the strength both parts of FBG.
Typical FWHM has a value 0.1nm ÷ 0.005 nm. Phase shifted FBGs are used as narrow bandwidth optical filter, for single-frequency fiber lasers creations. The experimental and theoretical transmission spectrum of FBGs is presented in the graph.
Applications
Fiber Bragg Gratings have many applications in optical communication, laser technique and sensing systems. FBGs are widely used in fiber mirrors or optical filters with narrow band optical spectrum. FBGs can be used as a sensitive element for strain and temperature measuring.
