TL;DR: The first epsilon-near-zero aluminum-doped zinc oxide (AZO) thin films that simultaneously exhibit ultrafast carrier dynamics (excitation and recombination time below 1ps) and an outstanding reflectance modulation up to 40% for very low pump fluence levels at a telecom wavelength of 1.3μm were presented in this article.

TL;DR: In this article, an all-optical aluminum doped zinc oxide (AZO)-based plasmonic modulator achieving 3 dB modulation in 7.5 µm and operating at THz frequencies is numerically demonstrated.

TL;DR: A review of recent advances in various classes of near-zero-index (NZI) materials can be found in this article, with particular focus on homogeneous materials, including metals, semi-metals, doped semiconductors, phononic and interband materials.

TL;DR: In this paper, different material platforms for various applications of metasurfaces, including refractory plasmonic materials, epitaxial noble metal, silicon, graphene, phase change materials, and metal oxides, are discussed.

TL;DR: This roadmap is an effort to present emerging fronts in areas of optical metamaterials that could contribute and apply to other research communities by anchoring each contribution in current work and prospectively discussing future potential and directions.
