Researchers from the University of Illinois at Urbana-Champaign have demonstrated a new level of optical isolation necessary to advance on-chip optical signal processing. The technique involving light-sound interaction can be implemented in nearly any photonic foundry process and can significantly impact optical computing and communication systems.
Nature has inspired scientific and engineering innovations for hundreds of years. An apple falling from a tree inspired Isaac Newton to define the laws of gravity. The burdock burrs clinging to the skin of his hunting dog lead to Swiss engineer Georges de Mestral’s invention of Velcro. The ability of the kingfisher to slice through water to catch prey inspired the redesign of the high-speed Japanese Bullet Train, enabling it to exit tunnels quietly at a speed ten percent faster than predecessors.
