Advertisement Imaging in the fast lane  The rapidFLIM approach to fluorescence lifetime imaging allows acquiring images at high speeds by exploiting recent hardware developments. At speeds of more than 15 images per second, the study of dynamic processes becomes possible, including protein interactions, chemical reactions, or highly mobile species.

The symposium will take place at the upcoming Metamaterials'2017 conference in Marseille, 28 August — 2 September.  FIND OUT MORE Subscribe   Facebook   RSS   Recommend to library   Twitter   Editorial Top A legacy for lasers   p265 doi:10.1038/nphoton.2017.67 Ronald Drever may be most famous for co-founding the LIGO project and his gravitational-wave research, but his contributions to laser stabilization have had broad impact on the photonics community. Books and Arts Top New titles at a glance   p266 2D Materials Edited by Phaedon Avouris, Tony F. Heinz and Tony Low doi:10.1038/nphoton.2017.61 Research Highlights Top Optical lattices: Reconfigurable ratchet | Free-electron lasers: Terahertz spectrometer | Imaging: Quantum time lens | Nanoscopy: Scrutinizing nanowires | Metamaterials: Reverse Cherenkov News and Views Top Optoelectronics: Fast silicon photodiodes   pp268 - 269 Michael B. Johnston doi:10.1038/nphoton.2017.58 There is typically a compromise between speed and efficiency when designing silicon photodiodes. Now, researchers have exploited microstructuring to achieve fast and thin devices that are also efficient. See also: Article by Gao et al. Metamaterials: A low-energy Cherenkov glow   pp269 - 271 Mário Silveirinha doi:10.1038/nphoton.2017.59 Hyperbolic metamaterials are shown to enable the emission of Cherenkov radiation from low-energy charged particles travelling at slow speeds. The achievement could lead to new forms of light sources and detectors. See also: Letter by Liu et al. View from... JSAP Spring Meeting: A marriage of materials and optics   pp271 - 273 Noriaki Horiuchi doi:10.1038/nphoton.2017.62 A laser-annealing technique for increasing the dopant concentration in semiconductors, the creation of a glass with second-order optical nonlinearity and the realization of optical topological insulators were highlights at the Japan Society of Applied Physics Spring Meeting.

Here, silicon-based metamaterial and nanophotonic advances are reviewed. Letters Top Spatially segregated free-carrier and exciton populations in individual lead halide perovskite grains   pp285 - 288 S. Nah, B. Spokoyny, C. Stoumpos, C. M. M. Soe, M. Kanatzidis et al. doi:10.1038/nphoton.2017.36 A study of single grains of lead halide perovskite reveals the presence of both excitons and free charge carriers. Integrated Cherenkov radiation emitter eliminating the electron velocity threshold   pp289 - 292 Fang Liu, Long Xiao, Yu Ye, Mengxuan Wang, Kaiyu Cui et al. doi:10.1038/nphoton.2017.45 Researchers use hyperbolic metamaterials to make an integrated Cherenkov light source and relax the electron energy requirements. Radiation covering the visible range and near-infrared is achieved with electron energies of only 0.25–1.4 keV.
