A new fabrication technique for corrugated longperiod fiber gratings (CLPFGs) with periodic polymer microstructures is proposed. Transmission characteristics of CLPFGs are improved by changing the applied strain because of the control of the coupling strength. The sensitivities of strain, torsion and ambient refractive index were measured.
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.
