ランダムレーザー光源を用いたスペックルフリー・レーザーイメージング
Speckle-free laser imaging using random laser illumination pp355 - 359
Brandon Redding, Michael A. Choma and Hui Cao
doi:10.1038/nphoton.2012.90
Exploiting the low spatial coherence of specifically designed random lasers, researchers demonstrate speckle-free full-field imaging in the regime of intense optical scattering. Their results show that the quality of images generated from random-laser illumination is superior to those generated from spatially coherent illumination.

エコー式高調波発生自由電子レーザーの初のレージング
First lasing of an echo-enabled harmonic generation free-electron laser pp360 - 363
Z. T. Zhao et al.
doi:10.1038/nphoton.2012.105
Lasing in X-ray free-electron lasers is typically achieved by self-amplification of spontaneous emission, which is known to have non-ideal temporal coherence and suffer from beam fluctuations. Here researchers report lasing based on echo-enabled harmonic generation at the Shanghai Deep Ultraviolet free-electron laser facility.

ハイブリッド光検出器の完全量子トモグラフィーによる測定においてコヒーレンスをマッピングする
Mapping coherence in measurement via full quantum tomography of a hybrid optical detector pp364 - 368
Lijian Zhang et al.
doi:10.1038/nphoton.2012.107
By developing full quantum detector tomography, researchers simultaneously characterize the wave- and photon-number sensitivities of quantum-optical detectors to yield the largest ever parametrization in a quantum tomography experiment. The presented results reveal the role of coherence in quantum measurements and demonstrate the tunability of hybrid quantum-optical detectors.

シリコンチップ上に化学的にエッチングした超高Qくさび型共振器
Chemically etched ultrahigh-Q wedge-resonator on a silicon chip pp369 - 373
Hansuek Lee et al.
doi:10.1038/nphoton.2012.109
Using only conventional semiconductor processing on a silicon wafer, researchers successfully fabricate an on-chip resonator with a record Q-factor of 875 million − around 20 times higher than previous results. They also demonstrate stimulated Brillouin lasers as an example application to emphasize the size control feature of the fabrication method and the ultrahigh-Q available from these resonators.

条件付きヌリング受信機を用いた標準量子限界未満の誤り率での光学的コードワード復調
Optical codeword demodulation with error rates below the standard quantum limit using a conditional nulling receiver pp374 - 379
Jian Chen et al.
doi:10.1038/nphoton.2012.113
Researchers experimentally demonstrate the first joint-detection receiver capable of performing a joint measurement over pulse-position-modulation codewords. This result - the largest improvement over the standard quantum limit reported to date - is accomplished by using a conditional nulling receiver, which uses optimized-amplitude coherent pulse nulling, single-photon detection and quantum feedforward.

不可視の金属‐半導体光検出器
An invisible metal-semiconductor photodetector pp380 - 385
Pengyu Fan et al.
doi:10.1038/nphoton.2012.108
Researchers demonstrate a silicon nanowire photodetector whose gold electrical contacts render the device 'invisible'. The wire and gold coating have opposing dipole moments that almost cancel each other out in the far-field. Although the net dipole moment is zero, a significant photocarrier population is generated in the wire.

中性粒子のレーザー駆動加速
Laser-driven acceleration of neutral particles pp386 - 390
C. Maher-McWilliams, P. Douglas and P. F. Barker
doi:10.1038/nphoton.2012.87
Researchers accelerate neutral-charge atoms from rest to a speed of 191 m s-1 over a distance of 10 [micro]m in 70 ns. This method is applicable to many atomic and molecular species, including those without permanent electric or magnetic dipole moments, which is a requirement of some alternative techniques.

Researchers demonstrate, in both normal and degenerate rat retinas, a photovoltaic subretinal prosthesis in which the silicon photodiodes in each pixel receive power and data through pulsed near-infrared illumination.

Why do we need statements to define the contributions made by each author? Does this practice help or hinder scientists, and which demographic is most affected?

The perils of solar cell efficiency measurements pp337 - 340
Henry J. Snaith
doi:10.1038/nphoton.2012.119
Ignorance and negligence are frequently causing solar cells to be mischaracterized, and invalid efficiency results have been reported in a number of journals. This problem can be greatly alleviated by employing a few simple precautions and guidelines.

Artificial vision: Solar cells for the blind pp344 - 345
Eberhart Zrenner
doi:10.1038/nphoton.2012.114
Electronic implants have been used to restore visual function lost as a result of retinal degeneration. Combining subretinal high-pixel-density arrays with optically powered serial photovoltaic sensors may alleviate some of the difficulties associated with today's devices, which rely on implanted arrays and inductive coils.
