Nanoscale motion sends light into overdrive

AMOLF researchers have developed nanoscale strings whose motion can be converted to light signals with unprecedented strength. This could allow for extremely precise sensors and comes with an important side effect. "Analogous to a guitar amplifier in overdrive producing distorted sound waves, our strong motion-to-light conversion leads to distorted light signals," says group leader Ewold Verhagen. "But these signals actually carry information about the motion that may lead to new ways of measuri
