The intriguing physics of vanadium dioxide (VO₂) makes it not only a fascinating object of study for fundamental research on solid-state physics but also an attractive means to actively modify the properties of integrated devices. In particular, the exceptionally large complex refractive index variation produced by the insulator-to-metal transition of this material opens up interesting opportunities to dynamically tune optical systems. This Perspective reviews some of the exciting work done on VO₂ for nanophotonics in the last decade and suggests promising directions to explore for this burgeoning field.
