  1. Micro- and Nanostructured Surfaces for Selective Solar Absorption

    Iryna E. Khodasevych, Liping Wang, Arnan Mitchell and Gary Rosengarten

    Article first published online: 5 MAY 2015 | DOI: 10.1002/adom.201500063

    Structured surfaces allow wavelength-selective manipulation of electromagnetic properties, such as the absorption of visible and infrared radiation, via changes to the structural geometry affecting the resonance mechanisms. Various aspects of the design and fabrication of selective absorptive micro- and nanostructures from photonic crystals to metal–dielectric–metal slab arrays, metamaterials, and nanoparticle arrays are reviewed.

  2. In Situ Synthesis of Graphene with Telecommunication Lasers for Nonlinear Optical Devices

    Pulak C. Debnath, Jaehyun Park, Austin M. Scott, Junsu Lee, Ju Han Lee and Yong-Won Song

    Article first published online: 4 MAY 2015 | DOI: 10.1002/adom.201500104

    Graphene is synthesized directly onto optical fiber end facets in ambient conditions via irradiation with a continuous wave laser operating at conventional telecommunication band. A nickel layer deposited onto the optical fiber acts both as catalyst and carbon host for the interfacial growth of graphene. The entire fiber–graphene device is used as passive mode-locker in a fiber laser ring cavity to generate ultrashort laser pulses.

  3. Curvature-Driven, One-Step Assembly of Reconfigurable Smectic Liquid Crystal “Compound Eye” Lenses

    Francesca Serra, Mohamed A. Gharbi, Yimin Luo, Iris B. Liu, Nathan D. Bade, Randall D. Kamien, Shu Yang and Kathleen J. Stebe

    Article first published online: 3 MAY 2015 | DOI: 10.1002/adom.201500153

    A self-assembly of microlenses on a curved interface can be obtained by pinning smectic liquid crystals around a micropillar with appropriate boundary conditions. This hierarchical structure of microlenses, with variable focal lengths from a few micrometers to a few tens of micrometers, is similar to an insect's compound eye; the lenses are reconfigurable with temperature and sensitive to light polarization.

  4. Demonstration of a 3D Radar-Like SERS Sensor Micro- and Nanofabricated on an Optical Fiber

    Zhenwei Xie, Shengfei Feng, Peijie Wang, Lisheng Zhang, Xin Ren, Lin Cui, Tianrui Zhai, Jie Chen, Yonglu Wang, Xinke Wang, Wenfeng Sun, Jiasheng Ye, Peng Han, Peter J. Klar and Yan Zhang

    Article first published online: 30 APR 2015 | DOI: 10.1002/adom.201500041

    Realization of the concept of “lab on fiber” based on 3D micro and nano architectures is achieved. A 3D radar-like surface-enhanced Raman scattering (SERS) sensor on an optical fiber is designed and created, which consists of a microparabolic mirror and a SERS body with its surface being metallized located at the focal point of the mirror.

  5. Plasmon–Phonon Interactions in Topological Insulator Microrings

    Marta Autore, Fausto D'Apuzzo, Alessandra Di Gaspare, Valeria Giliberti, Odeta Limaj, Pascale Roy, Matthew Brahlek, Nikesh Koirala, Seongshik Oh, Francisco Javier García de Abajo and Stefano Lupi

    Article first published online: 29 APR 2015 | DOI: 10.1002/adom.201400513

    Topological insulator Bi2Se3 microring arrays are investigated by means of terahertz spectroscopy. Both bonding and antibonding plasmon modes are observed in the spectra, together with a strong plasmon–phonon hybridization around 2 THz. An analytical theory is developed, which accurately describes the observed features. This work opens the road for the investigation and design of topological insulators-based plasmonic devices.
