摘要：
<正>In photonics, the quest for high-quality （high Q） resonances driven by the physics of bound states in the continuum （BIC）1,2 has motivated researchers to explore innovative avenues for realizing groundbreaking applications in lasing3, sensing4 and nonlinear photonics5. A conventional strategy to harness the properties of BICs involves breaking the symmetry of resonators in a uniform lattice, allowing uncoupled modes to interact with free space that opens a leaky channel in the form of socalled （quasi） q BIC6 modes.
