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 ...

Optical illusions have always fascinated me because they reveal how easily our brains can be tricked by simple patterns, color, design, and even different shapes and 3D models. When I first looked at ...

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 ...

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 ...
