Optical lenses have been playing a critical role in imaging systems for plentiful applications such as picture-capturing, sensing, and endoscopy. The developing wearable and portable devices require ...

An ultrathin dielectric metalens has been created that improves focusing capabilities but can also be scaled down to a tiny size for integration with photonics equipment. A metalens uses a metasurface ...

The key to harnessing the potential power of quantum systems is being able to create or find structures that allow electron spin to be reliably manipulated and measured, a difficult task considering ...
