A silicon metasurface design achieves record-breaking Q factor of 2750 for EIT-like resonances in the near-IR, by coupling two collective resonances—Mie dipole and electric quadrupole surface lattice resonances. This approach unlocks diverging Q factors and slow light via bound states in the continuum. The result: enhanced light–matter interactions on-chip, opening new frontiers for nanophotonic devices and quantum photonics.
