  1. Injection Molding of Free-Standing, Three-Dimensional, All-Metal Terahertz Metamaterials

    Free-standing two- and three-dimensional terahertz metamaterials are fabricated via injection molding of gallium, a metal that melts at temperatures just slightly above room temperature. The liquid metal is injected into elastomeric molds in which the desired geometry is inscribed. The metal does not solidify when cooled below the freezing temperature, but rather requires contact with a solid piece of gallium metal to do so.

    Highly transparent nanostructured gallogermanatebased glass and glass-ceramic materials are reported on page 364 by M. Allix and co-workers. These materials present nanoscale phase separations, whose size can be tailored depending on the nominal composition. The large variety of accessible compositions combined with precise control of the nanostructure offer a great opportunity to design new highly transparent nanostructured materials with a wide range of tuneable optical properties both in the visible and the infrared ranges.

  4. Optical Diodes: A Plasmonic Photonic Diode for Unidirectional Focusing, Imaging, and Wavelength Division De-Multiplexing (Advanced Optical Materials 4/2014) (page 354)

    Article first published online: 14 APR 2014 | DOI: 10.1002/adom.201470024

    A plasmonic photonic diode for unidirectional focusing, imaging, and wavelength-division de-multiplexing is achieved through the holographic imprinting of a discrete optical lens into metallic photonic crystals (MPCs). X. P. Zhang et al. focus laser beams of different colors to different angles and different focal lengths with a large dispersion using such a thin-film device. Realization of such functions is based on the spatial chirping of the MPCs, where the gold nanolines are arranged with different periods on different sites of the device.

  5. Photodetectors: Silicon-Based Visible-Blind Ultraviolet Detection and Imaging Using Down-Shifting Luminophores (Advanced Optical Materials 4/2014) (page 313)

    J. A. Rogers and co-workers exploit a design for visible-blind ultraviolet detection using silicon photodiodes and down-shifting luminophores. The fabricated device exhibits a selective UV response between 300 nm and 360 nm, which exceeds that in the visible range by about 103. An array of such detectors demonstrates the potential for using these structures in UV imagers, and suggests compatibility with large-area, CMOS-compatible Si electronics and photonics.
