  • Diffuse scattering can prevent high-resolution imaging in thick biological media. Researchers have now shown that such scattering can be completely cancelled by optical phase conjugation, opening the path to a new generation of medical imaging techniques.

  • Solar cells take advantage of our most abundant source of energy, the Sun. A technique that improves the conversion of photons to electrons could potentially lead to a dramatic improvement in device efficiency.

  • Non-reciprocal optical phenomena — effects that depend on the direction of light propagation — are rare. Researchers have now observed non-reciprocal material modification when moving a beam of ultrashort light pulses through a lithium niobate crystal.

  • Chains of coupled resonators are capable of dramatically slowing the speed of light. When all the resonators are identical light can, in principle, be stopped altogether. However, disorder causes light to move at a finite speed and to be localized over a few resonators.

Product Focus

  • Sensitive optical experiments and high-resolution microscopes often need to be mounted on vibration-control platforms to avoid unwanted disturbances to measurements. Neil Savage describes a selection of products designed for the task.

Interview

  • Conventional solar cells lose most of the Sun's energy as heat. Nature Photonics spoke to Tom Gregorkiewicz at the University of Amsterdam about his group's latest work, which may lead to cheap and efficient silicon solar cells by harnessing some of the lost energy.
