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 ...

Researchers have devised a new approach for controlling light in a silicon chip by bringing the concept of spatial light modulation to integrated optics. Silicon photonics are forming the backbone of ...

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.

Optical illusion puzzles are more than just fun internet distractions. These puzzles have been a part of daily lives since ...

Optical illusion puzzles have been there for centuries and these are fun challenges that are designed to play tricks on our eyes and brains. Optical illusions work on a simple principle where it ...

An Optical illusion is a type puzzle that creates a misinterpretation of the brain to the reality what out eys percieves and creating a false or misleading impression of reality. This occurs because ...

A teams of researchers from South Africa and Tunisia have demonstrated that adding light patterns to optical communications can bring significant bandwidth benefits. This new dimension in light ...

The basics of digital logic are pretty easy to master, and figuring out how the ones and zeroes flow through various kinds of gates is often an interesting exercise. Taking things down a level and ...

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 ...
