Research Highlights Top Sensors: Spinning object detection | Optoacoustics: Cleaving cells | Biophotonics: Single-cell transfection | Lens-free imaging: Opto-magnetics | Quantum optics: High-fidelity teleportation | Interferometry: Low-velocity measurement | Diode lasers: Excimer replacement | Artificial photosynthesis: Plant-like efficiency | Complex media: Subtle sensing | Metamaterials: Heating up News and Views Top Optical manipulation: Momentum exchange effect   pp765 - 766 Masud Mansuripur doi:10.1038/nphoton.2013.249 A pulling force can be generated via amplification of the photon linear momentum when a fairly uniform light field passes from one dielectric to another with a higher refractive index. This force can drag small objects over macroscopic distances along dielectric interfaces. Photonic crystals: Bridging the visible   p767 Noriaki Horiuchi doi:10.1038/nphoton.2013.255 Laser physics: Turbulent times   pp767 - 769 Fatih Ömer Ilday doi:10.1038/nphoton.2013.254 Researchers show that the breakdown of temporal coherence in a fibre laser has strong similarities with the onset of turbulence in fluids. Establishing a conceptual connection between these different systems can offer new perspectives for both fields. Stretchable LEDs: Light-emitting electronic skin   pp769 - 771 Michael Vosgueritchian, Jeffrey B.-H. Tok and Zhenan Bao doi:10.1038/nphoton.2013.251 Flexible electronics and optoelectronics have potential applications in energy generation, biomedicine, robotics and displays. Two recent demonstrations of highly stretchable polymer LEDs suggest that commercial devices may soon become viable. Plasma physics: Nanophotonics for plasma heating   pp771 - 772 Lap Van Dao and Peter Hannaford doi:10.1038/nphoton.2013.250 Vertically aligned nanowires on a solid surface in conjunction with table-top lasers create an ultrahigh-energy-density plasma with extremely high ionization in the laboratory. View from... CLEO 2013: A closer look at LIFE   pp772 - 774 Rachel Won doi:10.1038/nphoton.2013.270 Inertial fusion energy is one potential path towards realizing sustainable energy. The development of a laser power plant capable of delivering high-energy laser pulses is crucial for realizing laser-driven inertial fusion energy.

M. Hooker doi:10.1038/nphoton.2013.234 Laser-driven plasma accelerators have the potential to replace existing particle accelerators, as they are highly efficient systems that are orders of magnitude smaller than conventional particle accelerators. This review discusses recent progress and future challenges in this area. Letters Top The laminar-turbulent transition in a fibre laser   pp783 - 786 E. G. Turitsyna, S. V. Smirnov, S. Sugavanam, N. Tarasov, X. Shu et al. doi:10.1038/nphoton.2013.246 The transition between operation in a stable coherent state and that in a disordered turbulent state is studied in a fibre laser. The loss of coherence following the transition is associated with the appearance of solitons, which proliferate and cluster.

These forces arise from amplification of the photon linear momentum when light is scattered from one dielectric to another with a higher refractive index. They can manipulate objects over macroscopic distances along dielectric interfaces. See also: News and Views by Mansuripur Realization of an all-dielectric zero-index optical metamaterial   pp791 - 795 Parikshit Moitra, Yuanmu Yang, Zachary Anderson, Ivan I. Kravchenko, Dayrl P. Briggs et al. doi:10.1038/nphoton.2013.214 Previously demonstrated zero- or negative-refractive-index metamaterials at optical frequencies suffer from large ohmic losses because of the need to use metals. Metamaterials formed by stacked silicon rod unit cells allow the realization of all-dielectric impedance-matched zero-index metamaterials operating at optical frequencies, potentially benefiting the development of angular-selective optical devices. Relativistic plasma nanophotonics for ultrahigh energy density physics   pp796 - 800 Michael A. Purvis, Vyacheslav N. Shlyaptsev, Reed Hollinger, Clayton Bargsten, Alexander Pukhov et al. doi:10.1038/nphoton.2013.217 Femtosecond laser pulses were used to heat dense matter, converting it into an extremely hot plasma. 52-times ionized gold was achieved as well as gigabar pressures, which can be exceeded only in the central hot spots of thermonuclear fusion plasmas.

The prism-shaped device, which operates around the telecommunication wavelength of 1.5 μm, consists of a photonic crystal composed of an array of helical structures. Digitally synthesized beat frequency multiplexing for sub-millisecond fluorescence microscopy   pp806 - 810 Eric D. Diebold, Brandon W. Buckley, Daniel R. Gossett and Bahram Jalali doi:10.1038/nphoton.2013.245 A confocal fluorescence microscopy scheme that maps the image to the radiofrequency spectrum by beating together two optical fields offers enhanced read-out speeds at kilohertz frame rates. It provides a new way for observing dynamic phenomena in cells. Articles Top Ultrathin, highly flexible and stretchable PLEDs   pp811 - 816 Matthew S. White, Martin Kaltenbrunner, Eric D. Glowacki, Kateryna Gutnichenko, Gerald Kettlgruber et al. doi:10.1038/nphoton.2013.188 Ultrathin sheets of polymer LEDs that emit light even when being crumpled or stretched have been realized. The 2-[mu]m-thick devices emit red or orange light with a sufficiently high brightness for indoor applications, and they could prove useful for integration with textiles.

Elastomeric polymer light-emitting devices and displays   pp817 - 824 Jiajie Liang, Lu Li, Xiaofan Niu, Zhibin Yu and Qibing Pei doi:10.1038/nphoton.2013.242 A stretchable polymer LED is fabricated that is capable of emitting light when subjected to strains as large as 120%. A prototype 5 × 5 pixel monochrome display based on an array of these LEDs is demonstrated. See also: News and Views by Vosgueritchian et al. Polymer solar cells with enhanced fill factors   pp825 - 833 Xugang Guo, Nanjia Zhou, Sylvia J. Lou, Jeremy Smith, Daniel B. Tice et al. doi:10.1038/nphoton.2013.207 New designs of donor polymers yield organic solar cells with fill factors approaching 80%, significantly higher than those of conventional cells. This enhanced performance is attributed to the close-packed and highly ordered structure of the polymers PTPD3T and PBT13T, which leads to efficient charge extraction and suppressed recombination. Electromagnetic channel capacity for practical purposes   pp834 - 838 Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone and Jeffrey H. Shapiro doi:10.1038/nphoton.2013.193 The long-standing problem of determining the classical communication capacities of Gaussian bosonic channels is addressed by determining upper and lower bounds for the classical capacities of important active and passive bosonic channels. The results apply to any bosonic thermal-noise channel, including electromagnetic signaling at any frequency. Interview Top Turbulent transition   p840 Interview with Sergei Turitsyn doi:10.1038/nphoton.2013.269 Clustering of dark and grey solitons in fibre lasers has been found to induce a turbulent regime similar to that of a rapidly flowing fluid in a pipe.
