Every little investment, be it intellectual or financial, can potentially yield immeasurable returns. Commentaries Top Resolving a misconception about structured illumination   pp342 - 344 Kai Wicker and Rainer Heintzmann doi:10.1038/nphoton.2014.88 Applying structured illumination microscopy to coherent imaging modalities such as scattering does not yield any additional information beyond that provided by oblique illumination. It thus yields no resolution enhancement over the Abbe diffraction limit, which was derived precisely for that case. Making spatial multiplexing a reality   pp345 - 348 Peter J. Winzer doi:10.1038/nphoton.2014.58 To avoid a 'capacity crunch', future optical networks will need to simultaneously transmit multiple spatial channels. For spatial multiplexing to be practical, the upgrade path from legacy wavelength-division multiplexed systems needs to be smooth and to consider integration-induced crosstalk from the outset.

E. Northup and R. Blatt doi:10.1038/nphoton.2014.53 Recent advances in quantum information transfer by photons are reviewed. The theoretical framework for information transfer between nodes of a quantum network is described, and several key experiments for remote atom–atom entanglement mediated by light are illustrated. The prospects for hybrid systems currently in development are also discussed. Letters Top Experimental realization of a concatenated Greenberger-Horne-Zeilinger state for macroscopic quantum superpositions   pp364 - 368 He Lu, Luo-Kan Chen, Chang Liu, Ping Xu, Xing-Can Yao et al. doi:10.1038/nphoton.2014.81 With the help of two photonic controlled-NOT gates, a three-logical-qubit concatenated Greenberger-Horne-Zeilinger (C-GHZ) state encoded by a six-photon graph state is experimentally created. Observation of the dynamics of distillability evolving under a collective noisy environment revealed that the C-GHZ state is more robust than the conventional GHZ state. Diamond nonlinear photonics   pp369 - 374 B. J. M. Hausmann, I. Bulu, V. Venkataraman, P. Deotare and M. Lončar doi:10.1038/nphoton.2014.72 An optical parametric oscillator in the telecom wavelength range is realized in a diamond system consisting of a ring resonator coupled to a diamond waveguide. Threshold powers as low as 20 mW are measured and up to 20 new wavelengths are generated from a single-frequency pump laser. Coherent terabit communications with microresonator Kerr frequency combs   pp375 - 380 Joerg Pfeifle, Victor Brasch, Matthias Lauermann, Yimin Yu, Daniel Wegner et al. doi:10.1038/nphoton.2014.57 Kerr frequency combs are well suited for high-capacity data transmission with phase-sensitive modulation formats. This work demonstrates error-free transmission with data rates of up to 1.44 Tbit s-1, spectral efficiencies of up to 6 bit s-1 Hz-1 and transmission distances of up to 300 km. Gain dynamics in a soft-X-ray laser amplifier perturbed by a strong injected X-ray field   pp381 - 384 Y. Wang, S. Wang, E. Oliva, L. Li, M. Berrill et al. doi:10.1038/nphoton.2014.79 The first X-ray-pump-X-ray-probe measurement of the nonlinear response of a plasma amplifier perturbed by a ultrashort soft-X-ray pulse is demonstrated. Two time-delayed 18.9-nm-wavelength pulses were incident on a plasma, and the gain depletion induced by saturated amplification of the pump was measured with a femtosecond resolution.

Large-area luminescent solar concentrators based on 'Stokes-shift-engineered' nanocrystals in a mass-polymerized PMMA matrix   pp392 - 399 Francesco Meinardi, Annalisa Colombo, Kirill A. Velizhanin, Roberto Simonutti, Monica Lorenzon et al. doi:10.1038/nphoton.2014.54 Stokes-shift-engineered CdSe/CdS quantum dots are used to fabricate luminescent solar concentrators that are tens of centimetres long and do not exhibit reabsorption losses. With efficiencies of over 10% and an effective concentration factor of 4.4, they demonstrate the potential of using Stokes-shift-engineered quantum dots in large-area luminescent solar concentrators. Shape-induced force fields in optical trapping   pp400 - 405 D. B. Phillips, M. J. Padgett, S. Hanna, Y.-L. D. Ho, D. M. Carberry et al. doi:10.1038/nphoton.2014.74 Through shaping of colloidal particles, optical traps with prescribed force-displacement profiles are generated and are used to design a microscopic constant-force spring capable of delivering a constant piconewton-scale restoring force for displacements of several micrometres. Potential future applications include the imaging of sensitive biological membranes. Watt-class high-power, high-beam-quality photonic-crystal lasers   pp406 - 411 Kazuyoshi Hirose, Yong Liang, Yoshitaka Kurosaka, Akiyoshi Watanabe, Takahiro Sugiyama et al. doi:10.1038/nphoton.2014.75 Researchers demonstrate a watt-class high-power, single-mode photonic-crystal laser operating continuously at room temperature. A beam quality of M2 ≤ 1.1 is achieved. Tunable hot-carrier photodetection beyond the bandgap spectral limit   pp412 - 418 Yan-Feng Lao, A. G. Unil Perera, L. H. Li, S. P. Khanna, E. H. Linfield et al. doi:10.1038/nphoton.2014.80 By exploiting hot-carrier injection, the photodetection capabilities of a semiconductor structure have been extended to wavelengths as long as 55 µm, which is well beyond the usual spectral limits determined by energy levels. See also: Interview with Unil Perera Interview Top Hot-hole photodetectors   p420 Interview with Unil Perera doi:10.1038/nphoton.2014.91 By injecting high-energy charge carriers (dubbed 'hot holes') into a semiconductor, scientists have succeeded in realizing photodetectors capable of detecting ultralong wavelengths. Unil Perera from Georgia State University in the USA explains how the devices work and how they can be improved. See also: Article by Lao et al.
