SUPPLEMENTARY NOTES
ABSTRACTOptical links have many advantages over microwave links for a wide range of applications, including phased array radars, antennas, remoting, and microwave signal processing. Some major limitations in the deployment of optical links has been the large drive voltages, link loss, and limited linearity. The goal of the UCSB program was the demonstration of novel device concepts, innovative integration techniques, and interesting link concepts to address these issues. Significant contributions have been made in all these areas, including very low voltage traveling wave modulators with a Vr of 0.35 V, exceeding the program goal of 0.5 V, electroabsorption modulators integrated with tunable lasers, and novel links to simultaneously reduce the second and third order nonlinearity. The report provides details on devices, circuits, links, and their performance.
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.
