    While illuminated by a polarization-independent coherent laser source, the team’s metasurfaces generate ~10 K points over the entire 180-degree space. The depths of the dot arrays illuminated on the objects can be extracted using a stereo-matching algorithm.
    Nano-optical metasurfaces can give cell phones, augmented and virtual reality (AR/VR), and autonomous vehicles/robots a 360-degree view of their surrounding environment.

    FIGURE 1. The team split the energy of infrared ultrafast pulses to form ultrafast bursts of less intense pulses to improve localization of excitation. By using “fast enough” bursts, they accumulate enough energy to cross the material modification threshold and add new functionalities inside semiconductor chips.
    Researchers fabricate embedded structures inside semiconductor materials—demonstrating a 3D laser writing method’s potential to take semiconductor manufacturing from a largely...

    Simplified visible optical version of the quantum entanglement diagram disclosed by Pryce and Ward in 1947.
    While the well-known philosophical path toward quantum entanglement is conceptually attractive, it is fraught with hidden variable theories and paradoxes.

    Energized by green laser light, the color centers in diamonds have allowed the development of medical diagnostic techniques such as using quantum sensors for viewing brain tissue.
    Thanks to a German government-funded project, a new quantum sensor has the potential to make brain tumor procedures simpler, safer, and gentler.
