WebNov 7, 2024 · Avoided crossing of resonances and merging multiple bound states in the continuum (BICs) are parallel means for tailoring the physical properties of BICs. Herein, we introduce a new concept of super quasi-BIC for photonic crystal (PhC) systems where its quality () factor is boosted in both parametric and momentum spaces. Webversely, a wave state with the frequency inside the continuous spectrum can only be a resonance that leaks and radiates out to infinity. This is the conventional wisdom described in many books. A bound state in the continuum (BIC) is an exception to this conventional wisdom: it lies inside the continuum and coexists with extended waves, but it ...
