Optomechanical Nanobeam Cavity with High Q Factor due to Optical Spring Effect in Ambient Environment

Not Accessible

Your library or personal account may give you access

Abstract

High Q optomechanical cavity is demonstrated based on silicon nanobeam structure with mechanical frequency of 4.52GHz. The mechanical Q can reach 24500 with the help of optical spring effect, which is record-high in ambient environment.
