From: Robust high-Q filter with complete transmission by conjugated topological photonic crystals
The maximum value of quality factor and the transmittance versus the thickness filling factor variation for topological photonic crystals with different types. Type II* is conjugated, the parameters of the considered structure are nA = 3, nB = 1, nC = 1, nD = 3, ni = no =1, F1 from 0.26 to 0.39, F3 is conjugated with F1 variation. Type III is non-conjugated, the parameters of considered structure are nA = 3, nB = 1, nC = 1, nD = 3, ni = no =1, F1 from 0.26 to 0.39, F2 is fixed at 0.7.
