Supported by: Mars, Incorporated   Editorial Top Surface plasmon resurrection   p707 doi:10.1038/nphoton.2012.276 The realization that coupling of photons to charges at metal interfaces allows subdiffraction-limit localization of light has revived the field of surface plasmons. How long will it last? Correspondence Top A rocky road to plasmonic lasers   p708 Malte C. Gather doi:10.1038/nphoton.2012.281 Commentary Top Plasmonics for future biosensors   pp709 - 713 Alexandre G. Brolo doi:10.1038/nphoton.2012.266 Confinement and enhancement of light by plasmonics allows a high density of independent subwavelength sensor elements to be constructed in micrometre-sized arrays. It is relatively straightforward to integrate those sensors into microfluidics chips, making plasmonic structures promising for use in next-generation modern biosensors. Interviews Top Perspective on plasmonics   pp714 - 715 doi:10.1038/nphoton.2012.275 Joachim Krenn was one of the early pioneers of modern surface plasmon optics, and has almost 8,000 citations to his work. Nature Photonics spoke to Krenn about the field's origins.

Plasmonics: Diffraction-free surface waves   p720 Seiji Armstrong doi:10.1038/nphoton.2012.271 Optomechanics: Probing optical transitions   pp721 - 722 Gary A. Steele and Herre S. J. van der Zant doi:10.1038/nphoton.2012.270 Instead of using light to study mechanical motion, scientists have now demonstrated the use of mechanics to probe light, using an excitonic optomechanics coupling that paves the way to the implementation of cavity-free optomechanics. Quantum networks: A future without long memories?   pp722 - 724 Nicolas Sangouard doi:10.1038/nphoton.2012.268 An innovative quantum network design that uses light-matter interfaces to process individual light quanta may ultimately allow quantum communication at high rates and over long distances without the need for long-lived quantum memories.

This article reviews the development of active plasmonic devices and new metrologies using hybrid multilayer structures combining with the magnetic, acoustic and ultrafast effects. Nonlinear plasmonics   pp737 - 748 Martti Kauranen and Anatoly V. Zayats doi:10.1038/nphoton.2012.244 One of the main features of plasmonics is the possibility to locally enhance the intensity of electromagnetic fields. This enables strong nonlinear optical effects in structures with metal inclusions, including metamaterials. This Review discusses nonlinear effects in plasmonic structures and presents an overview of applications and limitations. Graphene plasmonics   pp749 - 758 A. N. Grigorenko, M. Polini and K. S. Novoselov doi:10.1038/nphoton.2012.262 Many researchers hope to merge plasmonics and graphene photonics to combine their useful features. The properties and characteristics of plasmons on graphene are reviewed. Prospects for possible future applications are discussed. Letters Top Non-polarizing broadband multilayer reflectors in fish   pp759 - 763 T. M. Jordan, J. C. Partridge and N. W. Roberts doi:10.1038/nphoton.2012.260 The mechanism by which various species of silvery fish produce almost perfect broadband, polarization-neutral reflections is revealed. The answer lies with the use of multilayers composed of two types of birefringent guanine crystals, which each have their extraordinary and ordinary refractive indices orientated in different directions. See also: Interview with Nicholas Roberts A proposal for multi-tens of GW fully coherent femtosecond soft X-ray lasers   pp764 - 767 E. Oliva, M. Fajardo, L. Li, M. Pittman, T. T. T. Le, J. Gautier, G. Lambert, P. Velarde, D. Ros, S. Sebban and Ph. Zeitoun doi:10.1038/nphoton.2012.246 Researchers describe a path towards 5 × 1014 fully coherent soft X-ray photons in 200 fs pulses reaching 20 GW peak power. The proposed amplification scheme is based on seeding stretched high harmonics using a transposition of Chirped Pulse Amplification to soft X-rays. See also: News and Views by Nagler A high-resolution microchip optomechanical accelerometer   pp768 - 772 Alexander G. Krause, Martin Winger, Tim D. Blasius, Qiang Lin and Oskar Painter doi:10.1038/nphoton.2012.245 Researchers demonstrate a chip-scale optomechanical accelerometer with displacement read-out using a photonic crystal cavity integrated with a tethered nanogram test mass of high mechanical Q-factor. The device achieves an acceleration resolution of 10 µg Hz-1/2 for sub-mW optical power, a bandwidth greater than 20 kHz, and a dynamic range of 50 dB. Experimental realization of Shor's quantum factoring algorithm using qubit recycling   pp773 - 776 Enrique Martín-López, Anthony Laing, Thomas Lawson, Roberto Alvarez, Xiao-Qi Zhou and Jeremy L. O'Brien doi:10.1038/nphoton.2012.259 By using qubit recycling, researchers demonstrate a scalable version of Shor's algorithm in which the total number of qubits is one third of that required in the standard protocol. They experimentally implemented a two-photon compiled algorithm to factor N=21, pointing to larger-scale implementations of Shor's algorithm. Articles Top Quantum communication without the necessity of quantum memories   pp777 - 781 W. J. Munro, A. M. Stephens, S. J. Devitt, K. A. Harrison and Kae Nemoto doi:10.1038/nphoton.2012.243 Researchers propose a design of quantum communication based on directly transmitting quantum information in encoded form across a network. Involving no teleportation, the scheme does not require entangled links between nodes and long-lived quantum memories. It potentially provides higher communication rates than existing entanglement-based schemes. See also: News and Views by Sangouard Realizing effective magnetic field for photons by controlling the phase of dynamic modulation   pp782 - 787 Kejie Fang, Zongfu Yu and Shanhui Fan doi:10.1038/nphoton.2012.236 By considering a resonator lattice in which the coupling constants between the resonators are harmonically modulated in time and by controlling the spatial distribution of the modulation phases, scientists introduce a scheme that can generate an effective magnetic field for photons, without the use of magneto-optical effects. Room-temperature mid-infrared single-photon spectral imaging   pp788 - 793 Jeppe Seidelin Dam, Peter Tidemand-Lichtenberg and Christian Pedersen doi:10.1038/nphoton.2012.231 Researchers experimentally demonstrate an upconversion system for field-deployable mid-infrared spectral imaging. The system provides a room-temperature dark noise of 0.2 photons per spatial element per second — a billion times below the dark noise level of cryogenically cooled cameras — and a quantum efficiency of 20%. Retraction Top Retraction: Polarization-entangled photons produced with high-symmetry site-controlled quantum dots   p793 Arun Mohan, Marco Felici, Pascal Gallo, Benjamin Dwir, Alok Rudra, Jérôme Faist and Eli Kapon doi:10.1038/nphoton.2012.274 Interview Top The fish that beat physics   p794 Interview with Nicholas Roberts doi:10.1038/nphoton.2012.273 Silvery fish have evolved an elegant optical scheme for overcoming the Brewster effect, creating broadband, polarization-neutral reflections for any angle of incidence. Nicholas Roberts explained to Nature Photonics how and why they do it. See also: Letter by Jordan et al.
