A new semipolar InGaN LED with an integrated metasurface produces circularly polarized light at 68% conversion efficiency, surpassing the 50% theoretical limit. By combining a semipolar InGaN ...

Circularly polarized light (CPL) plays an important role in various contemporary applications such as chiral molecule distinguishing, remote sensing, quantum optics, and spintronics. Traditional ...

A single gold nanorod, far smaller than a wavelength of visible light, can be coaxed into emitting circularly polarized radiation simply by nudging the electron beam that excites it a few nanometers ...

Tsukuba, Japan—Some beetles, such as Anomala albopilosa, strongly reflect left circularly polarized light (electromagnetic waves that oscillate leftward relative to the direction of light reception).

A device produces green light while a researcher in lab gear stands in the background. This OLED device, which is held by a mechanical support, is producing circularly polarized light. Credit: ...

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 ...

Researchers use circularly polarized light to control the direction of exciton polaritons in 2D semiconductors, enabling new tools for nanoscale photonics. (Nanowerk Spotlight) Directing light along ...

I am not an engineer, but I will offer an answer below. Any of our readers are invited to provide further clarification. A circular-polarized antenna is used to read tags in random orientation. The ...

I have a circuiar polarized filter for my S1 IS. I was told to get a UV Haze filter to cut out pollution. What is the difference? The circular polarized filter cuts out shiny surfaces. Can they be ...
