Abstract:In recent years, there has been an explosive growth of data traffic in datacenter interconnections. A significant amount of the installations within data centers are graded-index multimode fibers (GI-MMFs). These fibers enable the use of mode-division multiplexing to increase the fiber's capacity. The heart of such a multiplexing scheme is a spatial multiplexer. In this paper, we propose a simple tilted Gaussian beam multiplexer for GI-MMF using low-cost commercially available lenses. We derive an analytical e… 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.
