Conversely, the optical response of these systems is also  modified in the presence of mechanical interactions, leading to effects  such as electromagnetically induced transparency (EIT) and parametric  normal-mode splitting. In atomic systems, studies of slow and stopped  light (applicable to modern optical networks and future quantum  networks) have thrust EIT to the forefront of experimental study during  the past two decades. Here we demonstrate EIT and tunable optical delays  in a nanoscale optomechanical crystal, using the optomechanical  nonlinearity to control the velocity of light by way of engineered  photon\u2013phonon interactions. Our device is fabricated by simply etching  holes into a thin film of silicon. At low temperature (8.7 kelvin), we  report an optically tunable delay of 50 nanoseconds with near-unity  optical transparency, and superluminal light with a 1.4 microsecond  signal advance. These results, while indicating significant progress  towards an integrated quantum optomechanical memory, are also relevant  to classical signal processing applications. Measurements at room  temperature in the analogous regime of electromagnetically induced  absorption show the utility of these chip-scale optomechanical systems  for optical buffering, amplification, and filtering of  microwave-over-optical signals.<\/p>\n<h3>Related Images:<\/h3>","protected":false},"excerpt":{"rendered":"<p>Electromagnetically induced transparency and slow light with optomechanics from Nature by O.
