Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...
BEIJING -- A Chinese research team has developed a novel terahertz wave polarization modulator that can be used in multiple fields such as high-speed wireless communication, the Chinese Academy of ...
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 ...
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, ...
A new and quicker way of modulating the polarization of light pulses has been unveiled by researchers in the UK. The technique uses a second laser pulse to control polarization and could be used in a ...
