A light-trapping, color-converting crystal

A recipe for creating a microscopic crystal structure that can hold two wavelengths of light at once is a step toward faster telecommunications and quantum computers.

Developing technologies that run on light

Researchers are designing a nanoscale photon diode – a necessary component that could bring us closer to faster, more energy-efficient computers and communications that replace electricity with light.

Tiny light detectors work like gecko ears

By structuring nanowires in a way that mimics geckos’ ears, researchers have found a way to record the incoming angle of light. This technology could have applications in robotic vision, photography and augmented reality.

Stanford smart windows darken and lighten fast

New smart windows designed by Stanford engineers can change from transparent to dark or back again in under a minute depending on the light. The technology could be used in buildings, cars and even sunglasses.

High pressure key to lighter, stronger metal alloys

Subjecting complex metal mixtures called high-entropy alloys to extremely high pressures could lead to finer control over the arrangement of their atoms, which in turn can result in more desirable properties.
