A New Method to Enhance the Light–Matter Interaction by Controlling the Resonance of Electrons

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The paper focuses on simulating electron modulation in a hybrid structure consisting of interdigital electrodes, dielectric material, and doped semiconductor in the presence of an external field. However, the purpose of the simulation is unclear, despite references to potential sensor or light modulation applications.

Key points for consideration include:
1) Defining simulation error.
2) What is electron efficiency?
3) Establishing how simulated results can be validated through experiments
4) Noting that Table 1 lists parameters without corresponding simulation values in the paper.

With significant revisions, the paper may be suitable for publication in the journal Photonics.

Reviewer 2 Report

Comments and Suggestions for Authors

Dear Editor,

The authors have proposed a method to improve the modulation efficiency by enhancing the light-matter interaction. The manuscript needs to be revised as follows:

1. The introduction section is very poorly written. Various plasmonic modulators have been presented in recent years, which need to be added to the introduction section and their advantages and disadvantages need to be examined. There are also various interesting ideas and applications in plasmonic waveguide manipulation that have not been examined. Reading the following articles is necessary to use them in the introduction section.

Journal of Optical Communications 45, no. 3 (2024): 483-511; Advanced Functional Materials 33, no. 18 (2023): 2212328; Science Advances 10, no. 36 (2024): eadn5227; Optical and Quantum Electronics 55, no. 10 (2023): 894

2. In Figure 1, the light shines vertically, while to excite surface plasmons and move them, it must illuminate obliquely. Correct the angle of light incidence. For this figure, draw the coordinate axis. Put positive and negative signs on the electrodes, where you wrote is not correct.

3. The role of the electric field due to the electrodes in this work is not well and physically explained. This issue should be discussed physically.

4. The distribution of the electric field components of plasmons in the direction of propagation and the depth of the device is not drawn, while this figure is considered a necessity.

5. Important parameters such as propagation length, coupling length, figure of merit, and waveguide loss are not given. It is recommended that you calculate these parameters and compare them with the following articles to better evaluate the performance of the designed device.

Nanotechnology and Precision Engineering 7, no. 4 (2024); Optics & Laser Technology 157 (2023): 108680; Plasmonics 17, no. 3 (2022): 901-911; Design and Simulation of a Compact Subwavelength Graphene-Based Switch for Surface Plasmon Polariton Transmission in Integrated Optoelectronic Circuits." Plasmonics (2024): 1-13

6. How thick is the SiO2? The effects of contacts on the thin silicon layer are significant but have been neglected. Why?

 

Kind regards
