Renninger Lab (IMAGE) University of Rochester Caption Researchers at the University of Rochester, including optics graduate students Arjun Iyer (foreground) and Wendao Xu, designed acoustic cavities, or tiny echo chambers, to strongly couple surface acoustic waves with light. These devices are simple to fabricate, small in size, and have the ability to handle large amounts of power. Credit University of Rochester photo / J.
