We theoretically demonstrate a zero-refractive index medium (ZIM) based on Dirac cone metamaterials composed of an AlxGa1-xAs photonic crystal. This design allows us to achieve a waveguide medium with a very small phase advance. We validate our design further by demonstrating ZIM behavior using Snell’s law, such as the perpendicular refraction of light from a prism’s facet. This design paves the way for a monolithic platform that integrates zero-index physics with on-chip sources.
