Precision machining produces tiny, light-guiding cubes for advancing info tech

Drilling with the beam of an electron microscope, scientists have precisely machined tiny electrically conductive cubes that can interact with light and organized them in patterned structures that confine and relay light’s electromagnetic signal. This demonstration is a step toward potentially faster computer chips and more perceptive sensors. https://www.sciencedaily.com/releases/2022/01/220128141327.htm
