Reviewer 2 Report
In this paper, the authors present one review about phase-shifted fiber Bragg grating with special sensing characteristics and explore the influence of different inscription technologies on the sensing characteristics of PS-FBG by comparing the existing inscription methods. The sensing characteristics, advantages, and disadvantages of PS-FBG with different structures are analyzed. Phase shift FBG has some applications such review is nice for community interest in this topic. This review is clear, concise, and suitable for the scope of the journal. One main suggestion is supplied:
Suggest the authors add one application part, the title includes fabrication and application. Now the main focus is on the fabrication method.

Reviewer 3 Report
Authors presented a review of phase shifted FBGs. In general, the review is interesting, well organized and can help researchers in the optical fiber sensing fields. However, some adjustments are needed prior to the publication.
- There are many sentences in which a reference should be included. Such as the one about the transfer matrix method.
- Authors should include the spectra of the PS-FBGs obtained from the different methods discussed throughout the paper.
- Authors should include a critical comparison between the different PS-FBG fabrication methods discussed

Round 2
Reviewer 1 Report
In the reviewed manuscript, the authors addressed the comments reported after the first round of revision, apart from comment 11 in the cover letter where it is not clear the response.
The authors explained the meaning of the numbers in the matrix reported in Equation 1 of the manuscript only in the cover letter, but, in my opinion, they should add the explanation also in the manuscript.
Apart from the last comment above, I consider the manuscript suitable for publication in this journal.
