Reviewer 2 Report
In this article, authors present a novel taper in taper fiber (TITF) sensor, that has been covered with zinc oxide nanoparticles to achieve sensitivity.
In general paper is well written, the procedure for achieving the adequate shape is well presented. However, several comments are below:
- Authors do not discuss the issue of the tapered fiber adiabatic criterion. I believe that this is extremally important, since it may affect the responsitivity of the system, and its dynamics. Please review classical paper on that issue, presented in following research: https://doi.org/10.1109/50.134196
- Authors do not discuss novel concept related to the utilization of the taper as a sensor, with FBGs written in it. For instance, please review following research: https://doi.org/10.1364/OL.390784 & https://doi.org/10.1364/AO.442549
- I do have general question related to the repetability of the proposed concept, namely: 3 samples examination is little to low to confirm high repetability of the proposed method. Could authors comment on that? On Figure 6a there is no unit on y-axis, while on Figure 6b authors show normalized intensity - to what value those results have been normalized? Spectrometer readout value, or other?
- Please compare the results with other sensors that measures concentration, such as: https://doi.org/10.1364/AO.51.005941 or https://doi.org/10.1109/JSEN.2011.2138130
- There is lack of discussion on the temperature response of this fiber. Could authors discuss on that?
