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 ...

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 ...

FTIR spectroscopy remains a trusted workhorse for rapid, non-destructive molecular analysis, particularly for raw-material ...

Atoms emit unique light wavelengths when electrons change energy levels. A star's temperature and composition are revealed by its light spectrum. Strongest hydrogen lines appear in stars around 10,000 ...

SDSS-V marks a breakthrough in spectroscopic surveys, combining optical and near-infrared capabilities for extensive, ...

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 ...
