Integrated nano-cavity plasmon laser light-sources
Modern integrated circuits often need on-chip light sources for optical interconnects, but traditional off-chip lasers suffer from drawbacks such as large footprint, high energy consumption, slower modulation speeds, and inefficient coupling losses to on-chip waveguides. Existing approaches rely on III-V semiconductor lasers that are either separately...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...
