Ever wondered how tiny structures can do big things? Well, scientists have found a way to use tiny glass patterns, called dielectric metasurfaces, to detect changes in their environment. These patterns are so small that they can't be seen with the naked eye, but they can do something amazing: they can change how light passes through them based on what's around them. ...

Topology and physics have joined forces in the past ten years. They have uncovered many new things. One big discovery is topological insulators. These are materials that let electricity flow freely on their edges but not inside. This happens because of how the material is built at a tiny level. Another cool thing is twistronics. This is when scientists twist layers ...

Light is all around us, and scientists are always finding new ways to study it. Recently, they've made a big step forward with tiny lenses that can do what big, bulky machines used to do. These tiny lenses, called metalens arrays, can now look at light in a way that tells us a lot about its properties. The new tech uses a special material called TiO2 to make these t...

The world of optical communication is buzzing with a new discovery. It is about changing the way light behaves as it travels. This isn't just about making light go faster or slower. It's about changing how light waves interact with each other. This interaction can create unique patterns of polarization. Polarization is a fancy word for the direction in which lig...
