An ultrafast and ultralow-power on-chip-triggered all-optical switch is realized by X. Hu and co-workers. The device, which is described on page 1159, is based on a plasmon–photon–hybrid nanostructure-coated multicomponent nanocomposite in integrated photonic circuits. This paves a way to overcome the intrinsic material limitations for the realization of very-large-scale integrated photonic circuits and chips, and additionally provides a lab-on-chip platform for fundamental research of nonlinear optics and quantum optics.
