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 ...

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 ...

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 ...

Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where 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 ...

Reliably measuring the polarization state of light is crucial for various technological applications, ranging from optical communication to biomedical imaging. Yet conventional polarimeters are made ...

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: ...

With one slit, as you make the slit narrower, the spot behind it widens (and begins to look kind of like this, because one or two slits they behave like waves while in flight). When you have two slits ...
