How scattering light could power a microchip revolution
A research renaissance into chip-based control of light-sound interactions could transform our 5G and broadband networks, satellite communications, sensor technology and defense industries.
MechSE associate professor Gaurav Bahl co-authored a breakthrough review paper on the topic, published earlier this week in Nature Photonics.
"This paper outlines the rich physics that emerges from such a fundamental interaction as that between light and sound, which is found in all states of matter," Bahl said. "Not only do we see immense technological applications, but also the wealth of pure scientific investigations that are made possible. Brillouin scattering of light helps us measure material properties, transform how light and sound move through materials, cool down small objects, measure space, time and inertia, and even transport optical information."
