The Lightwave Research Laboratory is involved with multiple research programs on optical interconnection networks for advanced computing systems, data centers, optical packet-switched routers, and nanophotonic networks-on-chip for chip multiprocessors. We are developing a new class of nanoscale photonic interconnect technologies that seamlessly move data from on-chip networks, across memory and large computing systems with extreme energy efficiency. These future platforms, driven by nanophotonic-enabled interconnectivity, and the enormous bandwidth advantage of dense wavelength division multiplexing, will fundamentally transform the computation-communications architecture, to create systems able to meet explosive information demands at all scales.

Seeing Past Copper

As the computing world looks for ways to speed processing and reduce latency across various devices and systems, new and powerful frameworks are emerging. Many of these systems continue to run into the same vexing problem: the interconnects on microchips use electronic signals to transport data over copper wire between integrated circuits (IC).
