Single laser modulated drive and detection of a nano-optomechanical cantilever

Abstract

Nano-optomechanical systems (NOMS) offer many advantages in transducing nanomechanical motion. These include very high displacement sensitivities along with very large frequency detection bandwidths due to their optical nature [1]. It follows from this that NOMS are a promising avenue for on-chip nanomechanical mass sensing. Nanomechanical beams are becoming smaller to increase their mass sensitivity and nanophotonic detection is well suited to transduce these smaller devices [2].
