Abstract

The optomechanical interaction between photonic and phononic waves in micron scale devices is increasingly becoming important for ultrasensitive force and mass sensing applications. Diamond is an exception material for the coupling of optical and mechanical modes because of the low absorption in visible spectrum and high mechanical modulus. To generate optomechanical coupling it is essential to achieve mechanical resonances in the GHz range. Previous work has shown that it is possible to achieve acoustic band gaps at such high frequencies by high-order band gaps which exploit periodic structures with novel topologies. In this work we investigate how the topology and geometry of the periodic ..
