Combined Spectrometer / Microscope 
Time-resolved fluorescence spectroscopy is a valuable tool for investigating excited state dynamics in semiconductors. By interfacing a spectrometer like the FluoTime 300 with a microscope such as the MicroTime 100, one can easily record time-, space-, and spectrally resolved luminescence spectra.

Nature Outline: Quantum Computing 

Quantum computers are big news, but the quantum world can seem mysterious and confusing. In this Outline we explain the differences between classical and quantum computing, and suggest how quantum computers could transform science and technology.

Ultrafast photonics: Tailoring extreme-ultraviolet light   pp209 - 210
Taro Sekikawa and Kenichi L. Ishikawa
doi:10.1038/nphoton.2017.44
The emission direction and timing of extreme-ultraviolet light can now be manipulated through an opto-optical approach that uses an infrared pulse to control the spatial and spectral phase of free induction decay resulting from atoms excited by attosecond light.

Nonlinear optics: Attosecond nanophotonics   pp210 - 212
Giulio Vampa, Hanieh Fattahi, Jelena Vučković and Ferenc Krausz
doi:10.1038/nphoton.2017.41
Combining attosecond science and nanophotonics potentially offers a route to enhance control over light–matter interactions at the nanoscale and provide a promising platform for information processing.

Optical physics: Anisotropy enables unusual waves   pp212 - 214
Yuri Kivshar and Mikhail Rybin
doi:10.1038/nphoton.2017.42
It has been revealed that simple anisotropic optical waveguides and the vectorial nature of electromagnetic waves can support a variety of bound states in the continuum akin to those introduced in quantum mechanics almost a century ago.

Generation and multi-octave shaping of mid-infrared intense single-cycle pulses   pp222 - 226
Peter Krogen, Haim Suchowski, Houkun Liang, Noah Flemens, Kyung-Han Hong et al.
doi:10.1038/nphoton.2017.34
The conversion of shaped near-infrared pulses to shaped, energetic, multi-octave-spanning mid-infrared pulses lasting as little as 1.2 optical cycles is made possible by adiabatic difference frequency generation.

Symmetry-controlled temporal structure of high-harmonic carrier fields from a bulk crystal   pp227 - 231
F. Langer, M. Hohenleutner, U. Huttner, S. W. Koch, M. Kira et al.
doi:10.1038/nphoton.2017.29
The temporal structure of the polarization and carrier-envelope phase slip of high-harmonic waveforms generated in bulk gallium selenide within the duration of a single multi-terahertz driving pulse can be controlled by the crystal symmetry.

Anisotropy-induced photonic bound states in the continuum   pp232 - 236
Jordi Gomis-Bresco, David Artigas and Lluis Torner
doi:10.1038/nphoton.2017.31
Existence conditions of bound states within the continuum of radiative modes are revealed for waveguides with anisotropic birefringent materials.

Spatial beam self-cleaning in multimode fibres   pp237 - 241
K. Krupa, A. Tonello, B. M. Shalaby, M. Fabert, A. Barthélémy et al.
doi:10.1038/nphoton.2017.32
The Kerr effect in graded-index multimode fibres drives a spatial beam self-cleaning phenomenon that withstands fibre bending and does not necessitate dissipative processes such as stimulated scattering.

Femtosecond-laser-driven wire-guided helical undulator for intense terahertz radiation   pp242 - 246
Ye Tian, Jiansheng Liu, Yafeng Bai, Shiyi Zhou, Haiyi Sun et al.
doi:10.1038/nphoton.2017.16
Terahertz (THz) pulses are generated by irradiating a metal wire with femtosecond laser pulses. For incident laser energy of 3 mJ, a THz pulse with energy of 28 µJ is obtained from a 10-cm-long wire. The spectrum of the THz pulse covers 0.1–1.5 THz.

Single-photon imager based on a superconducting nanowire delay line   pp247 - 251
Qing-Yuan Zhao, Di Zhu, Niccolò Calandri, Andrew E. Dane, Adam N. McCaughan et al.
doi:10.1038/nphoton.2017.35
A superconducting nanowire acting as a single-photon detector and as a microwave delay line is used to demonstrate an imaging device at the single-photon level with sub-20-µm spatial resolution and 50-ps temporal resolution.

Space–time control of free induction decay in the extreme ultraviolet   pp252 - 258
S. Bengtsson, E. W. Larsen, D. Kroon, S. Camp, M. Miranda et al.
doi:10.1038/nphoton.2017.30
The spatial phase and direction of extreme-ultraviolet light are controlled by an all-optical modulator based on argon gas. It works by using an infrared pulse to control the spatial and spectral phase of the free induction decay in the gas system.

Subwavelength coherent imaging of periodic samples using a 13.5 nm tabletop high-harmonic light source   pp259 - 263
Dennis F. Gardner, Michael Tanksalvala, Elisabeth R. Shanblatt, Xiaoshi Zhang, Benjamin R. Galloway et al.
doi:10.1038/nphoton.2017.33
Coherent diffractive imaging of periodic samples is demonstrated with a tabletop, 13.5 nm high-harmonic source. With a novel image reconstruction technique, the record high spatial resolution of 12.6 nm is achieved in the extreme-ultraviolet region.
