“…As a consequence of the bandwidth enhancement and other beneficial characteristics offered by this approach, it has been the focus of over a hundred studies including Refs. [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] and is still attracting interest today as higher bandwidths are sought and new gain platforms explored [47].…”
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.
