Reviewer 1 Report
Increased interest towards 1 D photonic topological insulaotrs is receiveing more attention, the current article is interesting in particular for 1D topological photonic crystal (PhC) heterostructures. Reported high sensitivity with high Q factor and good high FOM is interesting to further explore in thie area of research.

Thanks for your comments.
Reviewer 2 Report
Authors constructed 1D topological photonic crystal mirror heterostructure, and showed optical properties. It is very interesting and manuscript is well written. The manuscript can be accepted after revision.
Below are my comments and questions.
- There is no mention about the boundary conditions of top and bottom parts. According to the electric field distribution, they did not consider it infinitely large. What are the boundary conditions?
- There is no mention about the polarization.
- Authors used 4 alternative layers. I think more layers will give higher Q but too many layers will eventually give no transmission. It is better to show Q vs. number of layers and transmission vs. number of layers.
- In figure 3 (b), I think one is symmetric mode and the other is anti-symmetric mode. It is not easy to see the symmetry with the norm of electric field. I think it is better to show the mode symmetry.
