The ability to control the speed of light on an optical chip is fundamental to the development of nanophotonic components for alloptical signal processing and sensing [1-7]. However this is a significant challenge, because chip-scale waveguides require very large changes in group index (Δng) to achieve appreciable pulse delays. Here, we use Stimulated Brillouin Scattering (SBS) to report the demonstration of on-chip slow, fast and negative group velocities with Δng ranging from -44 to +130, and...[Show more]
