Pulse Compression Using Fiber Bragg Gratings

Fiber Bragg gratings (FBGs) are one of the most important enabling technologies for fiber optics communications in the last decade. Their market growth was in 1995 and their use in telecommunications and sensors has grown largely. FBGs can be designed to have an almost arbitrary, complex spectral response, thus it has various applications in telecommunications. One of these important applications of FBGs is pulse compression or dispersion compensation. FBGs have been chosen to compensate dispersion among different techniques since it has low insertion losses. So, in this paper, two cases for dispersion compensation system using fiber Bragg gratings (FBGs) are proposed. First, a transmission-based system for dispersion compensation with no need for chirping or circulator so saving the insertion losses. Second, a reflective-based system, where chirping along with circulator should be employed. The results are validated by using Optical Grating (OptiGrating) software package.
