Research output: Contribution to journalConference articlepeer-review


We demonstrate lasing with ultralow threshold from small-scale dielectric metasurfaces with only ~10x10 periods operating at a super-BIC regime. Engineered high-Q resonance originates from topological merging of accidental and symmetry-protected bound states in the continuum.
