The liquid crystals that make phone screens glow are finding a second career: routing light signals inside computer chips. In ...
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device that can dynamically control the "handedness" of light as it passes ...
(Nanowerk News) Photonic time crystals consist of materials with uniform composition in space but properties that vary periodically over time. With this periodic variation, the spectral composition of ...
