Abstract

Graphene-like nanomaterials such as monolayer MoS2 have attracted considerable attention recently. In this article, we propose a nano-optomechanical system based on a suspended monolayer MoS2. The coherent linear and nonlinear optical properties of this system have been investigated theoretically. A scheme for measuring the coupling strength of exciton–nanoresonator and the frequency of the nanoresonator is also demonstrated by the optical pump-probe method. Based on the coherent optical spectrum, we further propose a nonlinear optical scheme to determine the mass of the biomolecules (such as single influenza virus and HIV virus). This scheme proposed here may have potential applications in quantum sensing and all-optical MoS2-based devices.
