Photonic metacrystals: design rules and applications

Photonic metacrystals are a class of photonic crystals that leverage deep subwavelength-engineering of the unit cell to synergistically combine metamaterials concepts with on-chip guided-wave photonics. This talk will present design rules for photonic metacrystals, highlighting the additional degrees of freedom in the design space that enable added control of light-matter interactions. Applications that can realize enhanced performance metrics using photonic metacrystals will be discussed, including on-chip modulators, optical biosensors, and optical nanotweezers. Perspectives on scalable foundry fabrication of photonic metacrystals will also be provided.
