Abstract

We report the observation of topological phonon transport within a multiscale optome-chanical crystal structure consisting of an array of over 800 cavity-optomechanical ele-ments. Using sensitive, spatially resolved optical read-out we detect thermal phonons in a 0.325-0.34 GHz band traveling along a topological edge channel, with substantial reduc-tion in backscattering. This represents an important step from the pioneering macroscopic mechanical systems work towards topological phononic systems at the nanoscale.
