Less is More: Extreme Optics with Zero Refractive Index, at Photonics West 2016, Integrated Optics: Devices, Materials, and Technologies XX (San Francisco, CA), Monday, February 15, 2016:
    Nanotechnology has enabled the development of nanostructured composite materials (metamaterials) with exotic optical properties not found in nature. In the most extreme case, we can create materials which support light waves that propagate with infinite phase velocity, corresponding to a refractive index of zero. This zero index can only be achieved by simultaneously controlling the electric and magnetic resonances of the nanostructure. We present an in-plane metamaterial design consisting of silicon pillar arrays, embedded within a polymer matrix and sandwiched between gold layers. Using an...
