Vision, microscopy, imaging, optical data projection and storage all depend on focusing of light. Dynamic focusing is conventionally achieved with mechanically reconfigurable lenses, spatial light ...

Researchers from the Southern University of Science and Technology, reporting on November 28, 2025, in Microsystems & Nanoengineering, describe a new optoelectrowetting-based droplet dispensing system ...

Image showing gold contacts where we bias each laser with DC current. Light is out-coupled from the racetracks using the directional-coupler waveguides along the straight section of either racetrack.

The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence ...

Researchers from the University of Southampton (UK), and the Institut d'Optique in Bordeaux (France) have devised a new approach for controlling light in a silicon chip by bringing the concept of ...

A flexible optical identifier uses polarized emission from self-assembled crystal films to create two stable states that support tri modal authentication and improve reliability in secure device ...
