  • Tiny lasers from a gallery of whispers

    Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a phenomenon similar to an effect observed in circular galleries, such as in some cathedrals or museums, where sound waves travel across the galler more

  • Water and light 'flow' inspire ultrasensitive optical microfiber coupler sensor

    When a river narrows or two rivers run into each other and merge, the water flow's speed increases and it becomes much stronger. Water flow and light flow are similar in many ways, and this inspired a group of researchers from Nanyang Technological University in Singapore and the University of Nebra more

  • Light-powered 3-D printer creates terahertz lens

    From visible light to radio waves, most people are familiar with the different sections of the electromagnetic spectrum. But one wavelength is often forgotten, little understood, and, until recently, rarely studied. It's called terahertz, and it has important applications in imaging and communicatio more
