Dispersion Compensating using Chirped Fiber Bragg Grating for Multiple Optical Bands

Abstract

Applications of fiber bragg gratings (FBG) in optical communication are a growing area. Recently, there has been a lot of interest in the creation and use of chirped FBGs, which are distinguished by a non-uniform modulation of the refractive index within an optical fiber core. Chromatic dispersion (CD) in pulse broadening and inter symbol interference (ISI) at the light detector significantly affect high-speed optical networks. The wavelength range where optical fibers have a low transmission loss is where fiber-optic communication is mostly carried out. Five wavelength bands make up this low-loss wavelength zone, which has a range of 1260 to 1625 nm. In this study we compared three different optical bands with different chirped FBG lengths to tackle the chromatic dispersion compensation containing 10 Gbps data speed. The single-mode fiber length and quality factor (Q) are minimally improved by the combination of four UFBG and CFBG design technique. By implementing quality factor (Q) of the available SMF are improved by using the combination. The best results have been seen for correcting chromatic dispersion by implementing quality factor (Q) of the available SMF are improved by using the combination. We consider Q-factor, eye diagram, and BER as a performance indicator of the system.
