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. Find out what happens within your sample!
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.
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.

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.
