Important instruments for neuroscience and medical diagnostics, optically pumped magnetometers measure responses of polarized atoms to produce information about the low-frequency external field. They ...

Cylindrical vector beam (CVB) multiplexing has emerged as a powerful technique to boost signal channels. Coupling and separating CVBs are two pivotal elements in CVB multiplexing communication.

Although the flashlight on an iPhone has worked incredibly well over the years, we’ve recently discovered what we’ve been missing — notably the ability to make the beam brighter, dimmer, wider, or ...
