Abstract:A photonic scheme to generate frequency sextupled microwave signal is proposed and experimentally demonstrated. An intensity modulator (IM) and a Sagnac loop with another IM imbedded inside are cascaded in the scheme. A light wave is modulated by a local oscillator (LO) signal in the first IM at the minimum transmission point to generate the ±1st‐order sidebands, and the modulated light wave is then sent to the Sagnac loop. The IM in the Sagnac loop is operating at the maximum transmission point and is driven … 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.
