Researchers at The University of Osaka, in collaboration with ULVAC, Inc. and Ritsumeikan University, have developed a new LED structure that generates circularly polarized light from a single chip.

A single gold nanorod, far smaller than a wavelength of visible light, can be coaxed into emitting circularly polarized ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

Light, as we usually conceive of it, is defined by the astonishing velocity at which it moves from one point to another. For ...

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.

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

So I've been familiar with the basics of polarization since forever, but I recently realized circular polarization is a mystery to me. I've heard of it in conjunction with eg satellite broadcasts, but ...

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

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...

An electromagnetic wave or signal traveling from “here” to “there” has an electrostatic field component that we call its E-field and whose direction we assign as the signal’s polarity. Often, the ...
