Researchers suppress optical back reflections, promising improved signals 11 Jan 2021 âNoise-cancellingâ principle adapted by team from Max Planck Institute, Imperial College London, and UK's NPL. An optical microresonator with a sharp tungsten tip. Click for more info.Microresonators are small glass structures in which light can circulate and build up in intensity. Due to material imperfections, some light is usually reflected backwards during operation, which disturbs the microresonator function. A UK-German research partnership has now demonstrated a method to suppress these un...
