Caltech’s “CUP2AI” makes two polarization measurements; in parallel and perpendicular to a test laser’s beam. Compressed Ultrafast Planar Polarization Anisotropy Imaging. Click for info. To understand ...

Coupled quantum dots can be an important building block in the development of scalable quantum devices by controlling the quantum states of two adjacent quantum dots (QDs) electrically and optically.

The finding, made possible by the application of ultrafast laser pulses, enriches fundamental physics research by advancing an understanding of the interactions between light and matter. The research, ...

Adjacent atomic layers slide across each other. Courtesy: M Ben Shalom Researchers have discovered a novel way of switching the polarization of an ultrathin ferroelectric material. The mechanism, ...

Physicists make unique broadband polarization rotators with ultrathin carbon nanotube films. The rotators extend to the terahertz, which could simplify devices for use in telecommunications, security ...

Piezoelectricity is a material’s capacity to transform mechanical energy (pressing) into electric energy (polarization) and vice versa. The word “piezo” derives from the Greek word piezein, which ...
