Recent advances in metamaterial silicon photonic devices and Huygens‘ metawaveguides

Metamaterial engineering has become established as an essential design tool in silicon photonics. The utilization of state-of-the-art semiconductor manufacturing methods to create metamaterials within optical waveguides has provided unparalleled control over the manipulation of light propagation in silicon photonic chips [1–6]. In this invited presentation, we will review recent breakthroughs in this rapidly advancing field. Additionally, we will introduce a nascent research area of resonant integrated photonics, leveraging Mie resonances in dielectrics for on-chip guidance of optical waves, as exemplified by the recent demonstration of the first Huygens’ metawaveguide [7].
