Scrutinizing lasers p139 doi:10.1038/nphoton.2017.28 Lasers play a pivotal role in photonics, but claims of lasing are not always as robust and informative as they should be. A new trial policy at Nature Photonics aims to rectify this shortcoming. |

Near-zero refractive index photonics pp149 - 158 Iñigo Liberal & Nader Engheta doi:10.1038/nphoton.2017.13 The underlying principles and unique optical applications of structures exhibiting near-zero dielectric permittivity and/or magnetic permeability are reviewed. The timely relevance to nonlinear, non-reciprocal and non-local effects is highlighted. |

Passively mode-locked laser with an ultra-narrow spectral width pp159 - 162 Michael Kues, Christian Reimer, Benjamin Wetzel, Piotr Roztocki, Brent E. Little et al. doi:10.1038/nphoton.2016.271 A passively mode-locked laser system featuring cavity filtering and cavity-enhanced nonlinear interactions within an integrated microring resonator produces nanosecond optical pulses with a spectral width of 104.9 MHz. |

Background suppression in fluorescence nanoscopy with stimulated emission double depletion pp163 - 169 Peng Gao, Benedikt Prunsche, Lu Zhou, Karin Nienhaus and G. Ulrich Nienhaus doi:10.1038/nphoton.2016.279 Stimulated emission double depletion addresses the issue of background in super-resolution imaging and quantitative microscopy through implementation of a two-pulse sequence in a modified stimulated emission depletion set-up. The measured background intensity is removed from each voxel in the acquired images thanks to time-resolved detection. |

Coherent backscattering of Raman light pp170 - 176 Barbara Fazio, Alessia Irrera, Stefano Pirotta, Cristiano D'Andrea, Salvatore Del Sorbo et al. doi:10.1038/nphoton.2016.278 Constructive interference is observed in the inelastically backscattered Raman radiation from nanostructured media. The effect is studied at a macroscopic scale and is explained in the context of Rayleigh–Raman random walks inside strongly scattering materials.

Highly efficient luminescent solar concentrators based on earth-abundant indirect-bandgap silicon quantum dots pp177 - 185 Francesco Meinardi, Samantha Ehrenberg, Lorena Dhamo, Francesco Carulli, Michele Mauri et al. doi:10.1038/nphoton.2017.5 Reabsorption losses in luminescent solar concentrators can be avoided by the use of indirect-bandgap semiconductor nanostructures. The technology has been used to demonstrate flexible luminescent solar concentrators with performance comparable to flat concentrators.

Charge-integrating organic heterojunction phototransistors for wide-dynamic-range image sensors pp193 - 199 Adrien Pierre, Abhinav Gaikwad and Ana Claudia Arias doi:10.1038/nphoton.2017.15 A solution-processed organic phototransistor is operated at 100-frame-per-second rates with external quantum efficiencies above 100%. Dynamic range as high as 103 dB was shown for 30-frame-per-second operation. |

Electric field-induced second-order nonlinear optical effects in silicon waveguides pp200 - 206 E. Timurdogan, C. V. Poulton, M. J. Byrd and M. R. Watts doi:10.1038/nphoton.2017.14 The application of d.c. fields across p–i–n junctions in silicon ridge waveguides leads to crystal symmetry breaking. This induces a second-order optical nonlinear susceptibility that enables phase-only modulation and second-harmonic generation with an efficiency of ∼13% W–1 at 2.29 µm. |
