Achieving Scalable Near‐Zero‐Index Materials

Abstract

Near-Zero-Index Materials Near-zero-index (NZI) materials show great promise for photonic devices by enabling new ways to control light–matter interactions. However, reproducibility and mass production of these materials have proven difficult. In article number 2200109, Jeremy N. Munday and co-workers describe how high-quality NZI materials can be obtained from commercial sources and used in novel devices and for fundamental photonics.
