Novel Measurement-Based Efficient Computational Approach to Modeling Optical Power Transmission in Step-Index Polymer Optical Fiber

Round 1

Reviewer 1 Report

In the paper “Novel measurement-based efficient computational approach to modeling optical power transmission in Step-Index Polymer Optical Fiber”, the authors propose an efficient computational model to estimate the most important parameters that determine the characteristics of light propagation through step-index polymer optical fibers which play an important role in industrial applications. The main goal of the proposed algorithm is to estimate the fiber characteristic functions (diffusion, attenuation, and mode group delay) as functions of the propagation angle from experimental measurements (intensity distributions and frequency responses) as functions of the fiber length. Two types of polymer fibers are used for the experimental verification. The first one is BH4001 which is a simplex fiber with a NA of 0.58 and a core refractive index of 1.49 (also called Eska Simplex High-Performance Plastic Optical Fiber Cable) and the second fiber is MH4001, which is a simplex fiber with a NA of 0.3 and a core refractive index of 1.49 (also called Eska Mega High-Performance Plastic Optical Fiber Cable). The authors developed the computational algorithm starting from Gloge’s power flow equation which is commonly used to solve such a problem. The key feature of the presented research is the high accuracy >97% in the estimation process.

The results are clearly presented and seem reliable and useful. The numerical results obtained by using the proposed algorithm are in a good agreement with experimental measurements. The paper is well-written, well-organized, and well-illustrated.

I have no suggestions on improving the paper.

Reviewer 2 Report

I don't have any bigger suggestions for Authors. The novelty is presented in a clear way. In my opinion the results section can be update with uncertainty calculation of the measurements.  

Author Response

Thank you for taking the time to review the manuscript and we would like to express our appreciation for your comments. We have made the following changes:

1. We have fixed the spelling errors throughout the manuscript.
2. About the suggestion of updating with uncertainty calculations the measurements in the result section, the frequency response measurements (Figures 4(a), and 4(c)), and optical power (Figures 6(a), and 6(b)) already show the error bars.  

Thank you once again for the constructive suggestions that we have incorporated into our revision.
