- In this work, an all-dielectric metamaterial is seen to act as nonlinear medium at optical telecommunications wavelengths, by harnessing the resonant nature of localized electromagnetic modes in a nanostructured silicon membrane. The authors 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. In this way, a path to fast, compact, and energy efficient all-optical metadevices is potentially created. Their sharply resonant nonlinear character may then serve a variety of sensing (e.g., gas pressure and chemical binding) applications.
