    Broadband microwave photonic fully tunable filter using a single heterogeneously integrated III-V/SOI-microdisk-based phase shifter 
    Lloret Soler, Juan Antonio; Morthier, Geert; Ramos Pascual, Francisco; Sales Maicas, Salvador; Van Thourhout, D.; Spuesens, T.; Olivier, N.; Fedeli, J.M.; Capmany Francoy, José (Optical Society of America, 2012)
    A broadband microwave photonic phase shifter based on a single III-V microdisk resonator heterogeneously integrated on and coupled to a nanophotonic silicon-on-insulator waveguide is reported. The phase shift tunability ...

    Engineering antenna radiation patterns via quasi-conformal mappings 
    García Meca, Carlos; Martínez Abietar, Alejandro José; Leonhardt, U. (Optical Society of America, 2011)
    We use a combination of conformal and quasi-conformal mappings to engineer isotropic electromagnetic devices that modify the omnidirectional radiation pattern of a point source. For TE waves, the designed devices are also ...

    Simultaneous existence of phononic and photonic band gaps in periodic crystal slabs 
    Pennec, Y.; Rouhani, B. Djafari; El Boudouti. E. H.; Li, C.; El Hassouani, Y.; Vasseur, J. O.; Papanikolaou, Nikos; Benchabane, Samir; Laude, Vincent; Martínez Abietar, Alejandro José (Optical Society of America: Open Access Journals, 2010-06-21)
    [EN] We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the centered square lattice and the boron nitride (BN) ...

    WDM-Coherent OCDMA over one single device based on short chip Super structured fiber Bragg gratings 
    Amaya Ocampo, Waldimar Alexander; Pastor Abellán, Daniel; Baños López, Rocío; García Muñoz, Víctor (Optical Society of America, 2011)
    We theoretically propose and demonstrate experimentally a Coherent Direct Sequence OCDMA en/decoder for multi-channel WDM operation based on a single device. It presents a broadband spectral envelope and a periodic spectral ...
