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 of PhC1 variation for topological photonic crystals with different types. All of the parameters are the same as those used in Fig. 4. Type II* is non-conjugated, F1 = 0.3, and F3 = 0.7. Type III is non-conjugated, F1 = 0.35, and F3 = 0.7.
