Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

In research published in APL Photonics, the team described using diamond crystals and the Raman effect—where laser light stimulates vibrations in materials and then scatters off those vibrations—to ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Infrared light passes through the metal lens and is converted into violet light and focussed in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.
