Abstract:SUMMARYOptical networks using singlemode fiber rely on negative chirp to improve the transmission performance. In particular for an electroabsorption modulator (EAM) optimal chirp control is required when it is used to achieve various network functions in high-speed optical networks. An approach to modelling the negative chirp for the EAM is presented that is suitable to apply to a cross-absorption modulation scheme. A novel feature of this modelling process is that it allows cubic polynomials to incorporate t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
