Whispering Gallery Goes Nanoscale

If you've been to a whispering gallery, a quiet, circular space often underneath a dome or vault that captures and amplifies sounds as quiet as a whisper, you have witnessed parabolics in action. The sound waves are efficiently propagated by the concave surface and similar whispering-gallery waves are evident in light. Researchers are applying similar principles in the development optomechanical sensors that will help unlock vibrational secrets of chemical and biological samples at the nanoscale. read more
