We deeply thank the reviewer for giving us this positive assessment.
Reviewer 2 Report (New Reviewer)
Comments and Suggestions for AuthorsThe authors presented a near-infrared Fabry-Perot cavity. This sounds interesting and I recommend its publication. The only shortage is there is only simulation, no experiments. If the authors presented some experiment results that agree with their simulation results, that would sound more interesting.

We deeply thank the reviewer for giving us this positive assessment. Unfortunately, we don’t have the relevant experimental equipment to fabricate the proposed cascaded Fabry-Perot cavities. We are very helpless for this situation. However, in our work, the parameters of Na and Sb2S3 that we used are experimental parameters, which can be found in the experimental articles [R1, R2].
At the end of Section 2 in the revised manuscript, we have added a paragraph to illustrate the fabrication scheme of the proposed cascaded Fabry-Perot cavities. The related sentences are “Finally, we discuss the fabrication scheme of the proposed cascaded Fabry-Perot cavities. The proposed cascaded Fabry-Perot cavities is a multilayer composed of Na and Sb2S3 films. It is known that both Na films [47] and Sb2S3 films [61] can be fabricated by the spin-coating technique. In addition, the crystalline fraction of Sb2S3 film can be flexibly controlled by the power density of a continuous-wave laser [50]. Therefore, the tunable near-infrared transparent band would be achieved using the spin-coating and the continuous-wave lasing technique.”.

This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsNew NIR multilayer filters on the base of Fabri-Perot resonators have been simulated and prototyped. Occurence of the near-infrared transparent bands is demonstrated. Influence of the layers number, incidence angle, layer thickness has been estimated.
The methods used are valid. The illustrations correspond to the text. As to references they are rather good, but a recent paper (Belyaev, V.; Zverev, N.; Abduev, A.; Zotov, A. E-Wave Interaction with the OneDimensional Photonic Crystal with Weak Conductive and Transparent Materials. Coatings 2023, 13, 712. https://doi.org/10.3390/ coatings13040712) describes a physical theory that can explain the effect obtained.
The English is satisgactory.

Reviewer 2 Report
Comments and Suggestions for AuthorsAuthors constructed a near-infrared Fabry-Perot cavity composed of two indium tin oxide layers and a silicon layer. This work is relatively simple. It is better to add more experiments to support the design. Therefore, I think this work is not suitable to publish in Photonics.
