Abstract: Optomechanical device for frequency doubling enhancement are described. The devices include a substrate through which light of a first wavelength is introduced, a first reflector mirror, a conductive layer disposed on the first reflector mirror, and a second mirror spaced apart from the conductive layer, thereby forming an optical cavity between the second mirror and the conductive layer. The devices also include a power source coupled to the second mirror and the conductive layer and a monolayer of non-linear optical material disposed within the optical cavity, the monolayer being configured to produce light of a second wavelength upon interaction with the light of the first wavelength. The second mirror is deformable upon introduction of voltage from the power source and deformation of the second mirror changes a length of the optical cavity, thereby enhancing a power output of the light of the second wavelength produced by the monolayer.
