Optical illusions are a fun and interesting way to challenge our brains and sharpen our observation skills. Sometimes, what we see at first glance is not the complete picture. There are hidden within ...

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 ...

Your eyes and brain don’t always agree with each other. Sometimes your brain fills gaps, ignores details, or assumes patterns that aren’t really there. That’s exactly why optical illusions feel so ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...

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 ...
