Abstract
Near-field interactions among quantum emitters can be leveraged to realize useful novel light sources. One example is superradiance, the cooperative enhancement of spontaneous emission, which enables lasing with high spectral purity. Here, we numerically demonstrate suppression of superradiance in atomic arrays resonant with the epsilon-near-zero region of a nearby indium tin oxide (ITO) thin film. By exploiting the field-effect tunability of ITO, we show how cooperative emission can be switched on and off using a simple gold-oxide-ITO thin-film structure.
