Abstract
We measure the spatial distribution of a topologically protected elastic modes in a silica 1D phononic crystal (PnC) by using the photoelasticity imaging technique. The strong localization of the topological elastic mode at the interface of two-joined PnCs with topologically distinct bandgaps is experimentally demonstrated.
