Winter weather looks intimidating, but freezing temperatures are not a good excuse to avoid movement. Most people—especially those without significant heart or lung conditions—benefit far more from ...

Adaptive optics is a branch of optics and photonics that uses light-controlling components to actively correct distortion in an incoming image. These distortions can occur when light from an ...

We fabricate a lithium niobate slot waveguide for THz field enhancement and demonstrate compact linear THz spectroscopy on an inserted sample. A hybrid metasurface functioning as a low-correlation and ...
