Physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarization of visible light by several degrees at certain wavelengths under small magnetic ...

Researchers from the University of Oxford have for the first time discovered an approach to electrically switch organic LEDs (OLEDs) to emit either left- or right-handed circularly polarized light ...

Release Summary Text: In atomically thin semiconductors, enhancing the frequency-doubled light signal has come at the cost of losing polarization information tied to the valley degree of freedom.

Light has always carried more than brightness. In this case, it also carries direction and twist. That mix may open a new ...

Scientists report a new method that achieves for the first time valley polarization in centrosymmetric bulk materials in a non-material-specific way. This 'universal technique' may have major ...

In a study published in Nano Letters, researchers demonstrated that light can change the electric polarization within the domains of a relaxor material in just trillionths of a second. Depiction of ...

By striking a gold nanorod off-center with an electron beam, researchers found a simple way to make light spin.

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

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 ...
