Switchable Metamaterial Devices In article number 2100244, Tian Jiang and co‐workers report a novel polarization‐coding all‐optical metadevice with a temporal dynamic modulation feature. The switching dynamic can be alternated between a quasi‐steady state with a recovery time larger than 2 ns and an ultrafast transient state with a recovery time less than 25 ps in two orthogonal polarization channels, which is believed to be a substantial advance in extending polarization multiplexing metadevices.
