Optical metamaterial reconfigured with sound
Optical metamaterial reconfigured with sound
We demonstrate that ultrasound vibrations cause linear and nonlinear changes of optical properties of nanomechanical metamaterials that are comparable to the magnitude of the optical properties themselves. We observe up to 73% linear acousto-optical reflectivity modulation in a metamaterial of only 100 nm thickness and substantial nonlinear acoustooptical modulation up to the sixth order. Our results indicate that acousto-optical metamaterials enable the miniaturization of acousto-optical technology by orders of magnitude and acoustooptics with extreme nonlinearity.

Abstract
We demonstrate that ultrasound vibrations cause linear and nonlinear changes of optical properties of nanomechanical metamaterials that are comparable to the magnitude of the optical properties themselves. We observe up to 73% linear acousto-optical reflectivity modulation in a metamaterial of only 100 nm thickness and substantial nonlinear acoustooptical modulation up to the sixth order. Our results indicate that acousto-optical metamaterials enable the miniaturization of acousto-optical technology by orders of magnitude and acoustooptics with extreme nonlinearity.
