Strain assisted multi-wavelength slicing utilizing distributed chirp fiber Bragg grating

Abstract In this paper, multi-wavelength slicing was investigated by employing chirp fiber Bragg gratings (CFBGs) under varied mechanical forces, The CFBGs exhibited multi reflections regions so, the obtained results showed generation 30 spectral lines with 0.8 nm channel spacing by slicing a broadband source over a wavelength range from 1,528 to 1,563 nm with a maximum optical signal to noise ratio (OSNR) of 21 dB was obtained at 1,558 nm. The band rejection is 10 nm around the central wavelength of CFBGs. The 30 optical lines are divided into two regions, each side having different spectral characteristics, where in the right side region, 12 lines appeared with a maximum peak power of 176.58 nW, while the left side region exhibited 18 lines with a maximum peak power of 138.601 nW. The statistical properties in terms of mean, variance, and standard deviation power that are 65.76 nW, 3.746 pW 2 , 61.21 nW, respectively, under applied mechanical force 0.981 N.Spectrum slicing with 30 optical lines suitable for dense wavelength division multiplexing (SS-DWDM), with an improved power Budget was obtained using mechanical forces, leading to enhancing the OSNR. and also system high compactness.
