A new patterned spintronic emitter enables room-temperature control of terahertz wave polarization.

Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass ...

Researchers from Beihang University in China have created a spintronic THz emitter with a microscale stripe pattern that ...

Light polarization is an interesting phenomenon that is extremely useful in many situations… but human eyes are blind to detecting any polarization. Luckily, [David] has built a polarization ...

Based on this film, the researchers constructed a single-shot, on-chip pol-PD without any additional polarization optics. In addition, the nanoimprinting crystallization method provides a novel ...
