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 ...

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 ...

Researchers have produced a record-thin optical quarter-waveplate from the two-dimensional material niobium oxychloride (NbOCl2), measuring roughly 269 nanometers thick and operating at a wavelength ...

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 ...
