Penn: Nanoplasmonic ‘whispering gallery’ breaks emission time record in semiconductors


Renaissance architects demonstrated their understanding of geometry and physics when they built whispering galleries into their cathedrals. These circular chambers were designed to amplify and direct sound waves so that, when standing in the right…

Penn researchers break light-matter coupling strength limit in nanoscale semiconductors


New engineering research at the University of Pennsylvania demonstrates that polaritons have increased coupling strength when confined to nanoscale semiconductors. This represents a promising advance in the field of photonics: smaller and faster circuits that…
