Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, ...

Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the ...

You've worn 3D glasses in cinemas, witnessing stunning depth as each eye sees a different image. You've put on polarized sunglasses in summer ...

Fig. 1 (a) Schematic of a PM that consists of two nanobeam cavities. (b) Normalized profile of the electric field (Ex at left and Ey at right) for the S and AS mode Polarization is an intrinsic ...

Physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarization of visible light by several degrees at certain wavelengths under small magnetic ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

For all its possibilities, nature tends to replay one particular scene over and over again: the confrontation between matter and light. It stages the scene in a practically infinite number of ways, ...

Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...
