On‐Chip Optical Switch Based on Plasmon–Photon Hybrid Nanostructure‐Coated Multicomponent Nanocomposite

An ultrafast and ultralow-power on-chip-triggered all-optical switch is realized based on a plasmon–photon hybrid nanostructure-coated multicomponent nanocomposite in integrated photonic circuits. This not only paves a way to overcome the intrinsic material limitations for the realization of very-large-scale integrated photonic circuits and chips, but also provides a lab-on-chip platform for the fundamental research of nonlinear optics and quantum optics.
