A new publication from Opto-Electronic Advances; DOI 10.29026/oes.2022.210014 overviews terahertz metasurface zone plates with arbitrary polarizations to a fixed polarization conversion. As an ...

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, ...

Based on a suitable band structure, the synergistic effect of oxygen vacancy defects and an electromagnetic field facilitates electron transfer. This process thereby achieves broadband absorption ...

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 ...

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 ...
