Natural gas leaks from production wells and pipelines pose a significant environmental risk due to the strong greenhouse effect caused by its main constituent, methane. We present a silicon photonic trace-gas sensing platform, which uses laser spectroscopy to realize cost-effective sensor networks for fugitive methane emission monitoring.
High-performance computing (HPC) systems capable of delivering Exaflops performance are envisioned to become a reality by the end of this decade. In order to provide the enormous communication bandwidth that is necessary, hundreds of millions of optical interconnects will have to be deployed to connect together racks, modules and chips. To achieve such… (More)
