Metamaterials, Nanophotonics & Integrated Photonics: State of the Field (October 2026)

Covers flat optics built from metasurfaces, high-Q and reconfigurable meta-optics, thin-film lithium niobate integrated photonics, and optical computing for AI workloads. The main takeaway is that metasurface optics have moved from single-function demonstrations toward visible and infrared imaging components, while integrated photonics is consolidating around thin-film lithium niobate, with heterogeneous and gain-integrated routes whose system-level benefits are still being measured.

Sample findings

  • A metasurface is a planar, subwavelength-structured layer that locally controls the amplitude, phase and polarization of light, and it can be patterned lithographically into thin optical components.
  • Generalized laws of reflection and refraction describe how abrupt phase discontinuities at a surface redirect light, which is the design basis of phase-gradient metasurfaces.
