    1. Deterministic separation of arbitrary photon pair states in integrated quantum circuits

      Ryan P. Marchildon and Amr S. Helmy

      Article first published online: 29 JAN 2016 | DOI: 10.1002/lpor.201500133

      Entangled photons generated within quantum circuits must often be spatially separated for their subsequent manipulation. While this is readily addressable in bulk optics, the full implications of using basic integrated photonics elements to achieve this separation is yet to be rigorously explored.

      This paper examines how dependencies of the integrated photonics components impact separation fidelity and interference visibility. This work informs device design for achieving universal photon pair separation for any two-photon state.

    2. A double-lined metasurface for plasmonic complex-field generation

      Eui-Young Song, Seung-Yeol Lee, Jongwoo Hong, Kyookeun Lee, Yohan Lee, Gun-Yeal Lee, Hwi Kim and Byoungho Lee

      Article first published online: 29 JAN 2016 | DOI: 10.1002/lpor.201500245

      A novel method for generating a plasmonic complex field propagating with arbitrary curvatures is proposed. As a unit cell, two facing nanoslits are used for tuning both the amplitude and the phase of excited SPPs as a function of their tilted angles. For verification of the proposed design rule, we experimentally demonstrate some plasmonic caustic curves and Airy plasmons.

    3. The onset of ultrashort pulse-induced nanogratings

      Felix Zimmermann, Anton Plech, Sören Richter, Andreas Tünnermann and Stefan Nolte

      Article first published online: 13 JAN 2016 | DOI: 10.1002/lpor.201500272

      Focusing ultrashort laser pulses in the bulk of silica allows for the localized generation of so - called nanogratings with sub-wavelength periodicity leading to artificial birefringence. By using different structural investigation techniques, the nanograting stepwise formation was studied comprehensively. Arising from deterministic voids, the onset of structure formation is dominated by laser-induced cracks along the scanned path followed by the growth of anisotropic sheets and mutual realignment into periodic grating planes.

    4. Broadband 10 Gb/s operation of graphene electro-absorption modulator on silicon

      Yingtao Hu, Marianna Pantouvaki, Joris Van Campenhout, Steven Brems, Inge Asselberghs, Cedric Huyghebaert, Philippe Absil and Dries Van Thourhout

      Article first published online: 11 JAN 2016 | DOI: 10.1002/lpor.201500250

      Graphene is considered to be a promising material for realizing ultra-high bandwidth and broadband operation electro-absorption modulators. However, demonstration of a graphene based modulator combining both properties in a single device is still lacking. In this work, the true potential of silicon integrated single layer graphene modulators is theoretically investigated and a broadband modulator operating at 10 Gb/s is demonstrated.

    5. Demonstration of local teleportation using classical entanglement

      Diego Guzman-Silva, Robert Brüning, Felix Zimmermann, Christian Vetter, Markus Gräfe, Matthias Heinrich, Stefan Nolte, Michael Duparré, Andrea Aiello, Marco Ornigotti and Alexander Szameit

      Article first published online: 11 JAN 2016 | DOI: 10.1002/lpor.201500252

      The authors present an extension of the concept of teleportation beyond the realm of quantum mechanics. The implementation is based on classically entangled beams of light solely. Teleportation has always been implicitly assumed to be inherently nonlocal, and therefore exclusive to quantum systems. The paper shows that this is not completely correct, as entanglement, rather than non-locality, is what defines teleportation, and non-locality only discriminates between its classical and quantum realizations.

    6. Identification and control of multiple leaky plasmon modes in silver nanowires

      Hangbo Yang, Min Qiu and Qiang Li

      Article first published online: 30 DEC 2015 | DOI: 10.1002/lpor.201500192

      Leaky plasmon modes in metal nanowires combine the physical characteristic of both “plasmonics” and “leaky radiation”, therefore presenting distinguished performances in terms of guiding and radiating light. Multiple leaky plasmon modes are crucial for advanced uses such as augmenting data transmission channels, enhancing sensing performance, manipulating polarization and converting mode. Here, control over multiple Leaky plasmon modes in pentagonal silver nanowires is experimentally demonstrated by combining far-field real-space imaging and leakage radiation microscopy.

      The generation of amplified spontaneous emission in high-power CPA laser systems

      Sebastian Keppler, Alexander Sävert, Jörg Körner, Marco Hornung, Hartmut Liebetrau, Joachim Hein and Malte Christoph Kaluza

      Article first published online: 30 DEC 2015 | DOI: 10.1002/lpor.201500186

      An analytical model is presented describing the temporal intensity contrast determined by amplified spontaneous emission in high-intensity laser systems. It includes both generation and amplification of the amplified spontaneous emission. Using this model, the requirements for an optimized high-contrast front-end design are derived regarding the necessary contrast improvement and the amplified “clean” output energy for a desired focussed peak intensity. The model will be an indispensable tool for the design of future high-power laser systems.

    8. Spectral engineering of coupled open-access microcavities

      L.C. Flatten, A.A.P. Trichet and J.M. Smith

      Article first published online: 20 DEC 2015 | DOI: 10.1002/lpor.201500138

      Thumbnail image of graphical abstract

      Open-access microcavities give direct access to a highly confined electromagnetic field while maintaining in-situ tunability and flexibility on the electronic system within. This article presents a study of coupled open-access cavities with volumes around inline image fabricated with Focused-Ion-Beam milling. The coupling between distinct photonic modes is analysed and compared to results from modemixing calculations. This work establishes a platform for engineered quantum photonic devices.
