Device Schematic (image) University of Pennsylvania Share Print E-Mail Caption Researchers at the University of Pennsylvania have engineered a nanowire system that could pave the way for photonic computing, combining two light waves to produce a third with a different frequency and using an optical cavity to amplify the intensity of the output to a usable level. Here, a schematic of the device.
