FIG 2 (IMAGE) Compuscript Ltd Caption Fig.2 Significant Q improvement in hybrid BIC lattices and robustness against fabrication imperfections. (a) Evolution of radiative Q versus asymmetry degree for U-qBIC, Ht-BIC, Hx-BIC and Hq-BIC lattices. The overall quality factors are improved in hybrid unit cells with a lower radiation density. (b) Influences of fabrication imperfection on quality factors in the four scenarios. Credit OES Usage Restrictions Credit must be given to the creator.
