Omnidirectional absorption in nanostructured metal surfaces - pp299 - 301

doi:10.1038/nphoton.2008.76

Light absorbers are not 100% efficient, and it is a challenge to absorb light completely for any direction of incidence. Using nanostructured metal surfaces, de Abajo and colleagues show that such omnidirectional absorption is now possible, potentially leading to more efficient solar cells.

Tuning the scattering response of optical nanoantennas with nanocircuit loads - pp307 - 310

Andrea Alù & Nader Engheta

doi:10.1038/nphoton.2008.53

Optical-frequency antennas efficiently couple light into very small volumes. Introducing an important concept from radiofrequency antenna design, that of loading with so-called lumped circuit elements, may provide a way of tuning the frequency response of optical nanoantennas.

Nanoscale optical microscopy in the vectorial focusing regime - pp311 - 314

doi:10.1038/nphoton.2008.29

It has been known for many decades that tightly focusing light introduces asymmetry. The impact of this on imaging, as is now demonstrated using solid immersion lenses, is that resolution becomes dependent on the polarization of the light.

Laser-generated plasmas are important for the creation of X-ray lasers and attosecond light pulses, but observing the internal dynamics of a plasma is difficult. This paper reports a method for real-time imaging of the electric-field distribution in such plasmas with ultrahigh temporal resolution, yielding a new insight into their behaviour
