By merging plasmonic metamaterials with quantum‐engineered inter‐subband transitions in a semiconductor heterostructure, M. A. Belkin and co‐workers have realized a 220‐nanometer‐thick electrically tunable mirror that can change its reflectivity in less than 10 nanoseconds in response to an applied electrical bias of a few volts. The broad tuning range of these mirrors is described on page 1057.
