Description
Fiber Bragg Gratings have many applications in optical communication, laser technique and sensing systems. The FBGs are widely used in-fiber mirrors or optical filters with narrow band optical spectrum. FBGs can be used like a sensitive element for strain and temperature measuring.

Features
The Apodized FBGs have special profile of induced refractive index and grating strength along the grating length. Therefore, side lobe level becomes smaller compared with that of the ordinary gratings. There are a lot of apodized profiles which lead to the optimization of various FBG parameters (strength, FWHM, SLSR).
Applications
Apodized FBGs are useful in sensing applications, signal and Brillouin scatter filtering and others. Possible values of SLSR for different grating strengths are in the range of -10dB to -30dB. The reflection spectrum of Apodized HR FBGs is presented in the graph.
