Global optimization of an encapsulated Si/SiO $$_2$$ 2 L3 cavity with a 43 million quality factor
Abstract We optimize a silica-encapsulated silicon L3 photonic crystal cavity for ultra-high quality factor by means of a global optimization strategy, where the closest holes surrounding the cavity are varied to minimize out-of-plane losses. We find an optimal value of $$Q_c=4.33\times 10^7$$ Q c =...
