WebSep 4, 2024 · FBG is widely used in beam steering application as well as in optoelectronic oscillator [ 8, 9 ]. There are various types of FBG which have been proven very much useful in remote sensing application [ 10, 11, 12 ]. These FBGs can be used for providing progressive phase shift and time delay in optical domain. WebHowever, the performance of the FBG sensor can be improved by engineering the distribution of the refractive index on the grid with the apodization and chirp functions. Apodization is a technique to improve the performance of the FBG to eliminate noise, narrow the full width half maximum, lower the side lobes of the main lobe, and improve …
