This study introduces multifunctional photonic crystals (PhCs) that integrate local wavefront control with nonlocal bound states in the continuum (BICs). This novel design unifies metasurface capabilities with PhC resonances for advanced optical applications.

Area of Science:

  • Photonics and Metamaterials
  • Flat Optics and Wavefront Shaping

Background:

  • Metasurfaces offer local control of light wavefronts.
  • Photonic crystals (PhCs) exhibit nonlocal resonances like bound states in the continuum (BICs).
  • Integrating these distinct optical regimes on a single platform is challenging.

Purpose of the Study:

  • To develop a single platform unifying wavefront shaping and BICs.
  • To create multifunctional photonic crystals by merging local and nonlocal optical phenomena.

Main Methods:

  • Embedding meta-notches within PhC pillars to create local control.
  • Utilizing spectral-zero-assisted topological phase for wavefront manipulation.
  • Preserving high-quality factor (Q) nonlocal BIC modes.
