Turning diffraction into a tool The technique uses a device that can only turn pixels on and off. Conventional thinking suggests that such a system can create only two levels of light intensity. The ...

A new research study from Opto-Electronic Advances discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography. In recent years, the scientific ...

A once purely mathematical tiling breakthrough has revealed an unexpected optical effect when recreated at the nanoscale.

"For us, it became an enabler." By carefully designing patterns smaller than the diffraction limit, the team was able to precisely control how much light reached different parts of the printing area ...
