A fully integrated 800 Gbps PAM-4 2×FR4 and DR8 silicon photonics transmitter with eight heterogeneously integrated DFB lasers is demonstrated for data center applications over a temperature range of 0~70°C and a reach of up to 2 km.
We propose an all-optical modulation format conversion method from binary phase-shift keying to quadrature phaseshift keying using a conventional delay line interferometer. We experimentally demonstrate error-free operation of the proposed conversion method at 12 Gb/s.
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.
