Optical antennas transform light from freely propagating waves into highly localized excitations that interact strongly with matter. Unlike their radio frequency counterparts, optical antennas are ...

Ultrafast extreme ultraviolet (XUV) spectroscopy is a powerful technique for probing the dynamics of atoms and molecules with attosecond time resolution. However, conventional XUV absorption ...

Plasmon-enhanced molecular spectroscopies have attracted tremendous attention as powerful detection tools with ultrahigh sensitivity down to the single-molecule level. The optical response of ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

The microseepage of gaseous hydrocarbons often creates a soil atmosphere containing lighter hydrocarbons (C1-C5). The gases in the soil may be sampled and analyzed to determine the specific mix of ...

Fraunhofer lines, discovered in 1814, are dark lines in the Sun's spectrum caused by the absorption of specific wavelengths of light by elements in the solar atmosphere, marking the birth of ...

Continuous-wave optical parametric oscillators emitting multiple watts of output power in the near- to mid-infrared are now a commercial reality. Angus Henderson of Aculight discusses the technical ...

When designing with interconnects, we're often concerned about issues such as crosstalk and reflections. We frequently ask for models from the manufacturers so we can run simulations to determine the ...
