Karvounis, A., Ou, J.Y., Wu, W. (2015). Nano-optomechanical nonlinear dielectric metamaterials. Applied Physics Letters, 107(19), article number 191110. doi: 10.1063/1.4935795
Abstract
By harnessing the resonant nature of localized electromagnetic modes in a nanostructured silicon membrane, an all-dielectric metamaterial can act as nonlinear medium at optical telecommunications wavelengths. We show that such metamaterials provide extremely large optomechanical nonlinearities, operating at intensities of only a few μW per unit cell and modulation frequencies as high as 152 MHz, thereby offering a path to fast, compact and energy
efficient all-optical metadevices.
