Abstract:We propose and experimentally demonstrate a reconfigurable finite impulse response microwave photonic filter (FIR-MPF) based on long period gratings (LPGs) inscribed in multicore fibers. By exploiting two dimensions of optical wavelength and space, intentional inter-core signal switching is realized. For the diversity of optical wavelength, we tune the operation wavelength to change the inter-core power coupling according to the wavelengthdependent characteristic of LPGs. On the other hand, for the diversity o… 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.
