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

Terahertz (THz) waves are located between microwaves and ... Critically, the device maintains high-quality circular polarization with an ellipticity greater than 0.85 across a broad frequency ...
