Dilute nitride (DN) vertical cavity surface emitting lasers (VCSELs) emitting near 1300 nm exhibit state-of-the-art performance including bandwidths of 10 GHz and a record high error-free data transmission of 12 Gbps. Renewed interest in DN VCSELs stems from emerging applications in kilometer-reach digital communication across optical fiber and across free space via eye safe beams, time-of-flight and structured light sensing, and photonic-electronic integrated circuit optical interconnects. We produce VCSEL wafers in a production molecular beam epitaxy system on 3- and 4-inch diameter GaAs wafers. We report record dynamic performance for our test VCSELs with oxide aperture diameters ranging from 2 to 12 µm.
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.
