Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow. The ...
Plasmonic structures exhibit a wide range of physical characteristics, which are benefited by the localized and intensified light–matter interaction. There have been many recent advancements with ...
Nonlinear optics describes the regime in which the response of a material to an applied electromagnetic field depends nonlinearly on the field amplitude. Whereas in linear optics the induced ...
Artistic rendering of noncollinear sum-frequency generation (SFG): two infrared pulses mix in a χ² crystal to produce three output pulses (green), with the central SFG pulse being the primary output ...
Optics & lasers as a research area encompasses the fundamental and applied study of the generation, propagation, manipulation, and detection of light, with a particular emphasis on coherent and ...
Scientists have pioneered a way to make integrated circuits for light by depositing complex patterns of specialized materials onto silicon wafers. (Nanowerk News) Computer chips that cram billions of ...
