A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...

Distributed fiber-optic sensing has become an indispensable tool for large-scale structural and environmental monitoring, where spectral interrogation of backscattering light enables high-precision ...

Ultrasonically-sculpted gradient-index optical waveguides enable non-invasive light confinement inside scattering media. The confinement level strongly depends on ultrasound parameters (e.g., ...

Every Wi-Fi router, FM radio station, and reading lamp relies on the same physical phenomenon: electromagnetic waves ...

Scientists at NPL have demonstrated the best-reported laser frequency stability achieved with an optical reference cavity operating at room temperature, marking a major advance in ultrastable laser ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Bright squeezed light, exhibiting sub-shot-noise quantum noise combined with significant optical power, is ...

All complex and intricate assemblies include components with natural frequencies that are critical because they exist in the generalized 8 to 200 Hz environmental spectrum. This can be demonstrated by ...

WASHINGTON — In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating clocks and the links connecting them simultaneously across six ...

This record-breaking crystal can transform from mirror-like to glass-like, opening the door to tiny optical chips, AR ...
