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 ...

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 ...

An optical illusion is a visual phenomenon where our perception of thinking about an image differs from objective reality. This image is seen as a Radiating Wavy Pattern Optical Illusion that appears ...

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 ...

Optical illusion puzzles are more than just fun internet distractions. These puzzles have been a part of daily lives since old times. Earlier these puzzles were presented in newspapers and now they ...

In today’s illusion, there is a hidden insect. By carefully adjusting your focus and observing the repeating patterns, it can ...

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 ...
