Nanometric holograms based on a topological insulator material

Holograms generally need to be as thick as a wavelength of light to introduce the necessary optical phase shifts that create true three-dimensional images. Here, Yueet al. use a high-index topological insulator material to create a resonant optical cavity and thin holograms to the nanometre scale.
