Dielectric corrugated waveguides are used in DFB and DBR lasers.Coupled mode theory is used to study the effect of variations in grating shape on the performance of DFB and DBR lasers. The purpose of this paper is to find the optimum geometry for different applications.
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.
