  1. Electro-/All-Optical Light Extraction in Gold Photonic Quasi-crystals Layered with Photosensitive Liquid Crystals

    Vincenzo Caligiuri, Luciano De Sio, Lucia Petti, Rossella Capasso, Massimo Rippa, Maria Grazia Maglione, Nelson Tabiryan and Cesare Umeton

    Article first published online: 17 JUL 2014 | DOI: 10.1002/adom.201400203

    A new concept photonic device is realized. It is based on the combination of unusual light control properties of a Thue-Morse nanopatterned photonic quasi-crystal with the extraordinary versatility of “smart” soft matter, represented by azo-liquid crystals. The device, which shows a dramatic polarization selectivity, can be tuned by exploiting either an electro-optical or all-optical mechanism.

  2. Light Harvesting: Near-Infrared Harvesting Transparent Luminescent Solar Concentrators (Advanced Optical Materials 7/2014) (page 599)

    Yimu Zhao, Garrett A. Meek, Benjamin G. Levine and Richard R. Lunt

    Article first published online: 15 JUL 2014 | DOI: 10.1002/adom.201470040

    A transparent luminescent solar concentrator that selectively harvests NIR photons is demonstrated. On page 606, R. R. Lunt and co-workers describe the photophysical and electronic properties of the luminophores, the impact of ligandhost control, and the optimization of the solar concentrator architectures to realize their potential for use in electronic displays, solar windows, and other glazing systems with high defect tolerances and processability.

  3. Magnetoplasmonics: Magnetoplasmonic Nanorings as Novel Architectures with Tunable Magneto-optical Activity in Wide Wavelength Ranges (Advanced Optical Materials 7/2014) (page 600)

    Hua Yu Feng, Feng Luo, Renata Kekesi, Daniel Granados, David Meneses-Rodríguez, Jorge M. García, Antonio García-Martín, Gaspar Armelles and Alfonso Cebollada

    Article first published online: 15 JUL 2014 | DOI: 10.1002/adom.201470041

    Au/Co/Au magnetoplasmonic nanorings present a bimodal spectral dependence of the magnetooptical activity, with maximum values in the visible and NIR regions. On page 612, the spectral positions of these maxima are tuned by F. Luo, A. Cebollada, and co-workers by modifying the structural parameters of the rings. This controlled modification of the magneto-optical activity of nanostructured systems may find interesting applications in areas like sensing, optical communications, and isolators.

  4. Microresonators: A New Route for Fabricating On-Chip Chalcogenide Microcavity Resonator Arrays (Advanced Optical Materials 7/2014) (page 696)

    Ozan Aktas, Erol Ozgur, Osama Tobail, Mehmet Kanik, Ersin Huseyinoglu and Mehmet Bayindir

    Article first published online: 15 JUL 2014 | DOI: 10.1002/adom.201470045

    Chalcogenides are promising materials for photonics due to their extraordinary optical properties. In order to achieve their full technological exploitation, they must be manufactured in photonic devices with various geometries necessitated by their unique optical functionalities. On page 618, M. Bayindir and co-workers develop a new route for the fabrication of on-chip photonic elements. This novel technique provides a low-cost, high-yield production method with a compatible and extendable integration phase.

  5. Hydrogels: Robust Mechanochromic Elastic One-Dimensional Photonic Hydrogels for Touch Sensing and Flexible Displays (Advanced Optical Materials 7/2014) (page 651)

    Xiao-Qiao Wang, Cai-Feng Wang, Zhen-Fang Zhou and Su Chen

    Article first published online: 15 JUL 2014 | DOI: 10.1002/adom.201470043

    On page 652, S. Chen and co-workers exploit a magnetic assembly technique for the fabrication of mechanochromic hydrogels sensitive in a low pressure regime. These photonic materials, made from 1D arrays of Fe3O4 nanoparticles immobilized in elastic hydrogels, show reversible wide color variation within 1 s through a compression-decompression process. Slight touches on the hydrogels, with pressures down to 1 kPa, can induce visual color changes, suggesting an alternative for flexible touch sensors and displays.
