摘要

Abstract

Light travels in a zero-index medium without accumulating a spatial phase

resulting in perfect spatial coherence. Such coherence brings several potential applications

including arbitrarily shaped waveguides

phase-mismatch-free nonlinear propagation

large-area single-mode lasers

and extended superradiance. A promising platform to achieve these applications is an integrated Dirac-cone material that features an impedance-matched zero index. Although an integrated Dirac-cone material eliminates ohmic losses via its purely dielectric structure

it still entails out-of-plane radiation loss

limiting its applications to a small scale. We design an ultra-low-loss integrated Dirac cone material by achieving destructive interference above and below the material. The material consists of a square array of low-aspect-ratio silicon pillars embedded in silicon dioxide

featuring easy fabrication using a standard planar process. This design paves the way for leveraging the perfect spatial coherence of large-area zero-index materials in linear

nonlinear

and quantum optics.
