Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

Butterflies can see more of the world than humans, including more colors and the field oscillation direction, or polarization, of light. This special ability enables them to navigate with precision, ...

Greetings stargazers. Everything we know about things outside of our solar system is from the light we receive. I am using ...

A novel differentiable approach optimizes geometric waveguide coatings, achieving substantial gains in light efficiency and ...
