Reviewer 2 Report
This work has practical applications in future optical devices. It seems interesting and well designed. I believe that the manuscript needs minor corrections.
In my opinion, figures 2f, 3-5 lack a gray vertical and horizontal grid, with the smallest possible line thickness. Something similar to that in Figure 1a. Let's say with a step of Pi/4. In this way, the Fraunhofer diffraction maxima, if their position changes, will be more clearly visible. It will also allow them to be identified more quickly.
It also raises the question of what exactly the distance between the diffraction maxima is, and whether it is the same for the same initial conditions?
It would also be desirable to make the same intensity color scale. Because it will allow you to compare them with each other.
On page 3, in the phrase "jth atom to attain ρ_j=Tr=j ρ [40]", the formula should be corrected.
In figure 2, you need to specify bibliographic references to all Relevant parameters.
In figure 5 insets show (imaginary and real) refer to which range? from (-1;1) along x-y or to the range in which they are located. If this is the first option, then it should be placed in the same place. Perhaps in the upper right corner of each figure. If they are in the same range as the diffraction maxima, then it would be good to add a schematic square around the diffraction maxima. It's also worth checking your data as on 5b the top left maximum is brighter yellow, while on the variance inset it's the bottom right. It seems to me that the inserts for "dispersion distributions plot" in 5b and 5d should be changed or explained.
Why the authors introduce the abbreviations CPT and LWI in the introduction, if they are not used later in the text.
In Figure 2c-d, what do the red and blue lines mean?
In figures 3-4, check the captions, because in the figure the upper pallets are numbered a-c-e and the lower pallets are b-d-f. In caption a-c is upper and d-f is lower.
In the figures, the authors give a variation of different sizes. For example, figure4, L = 100-400z_0. What determines the choice of such values?, which are possible minimum and maximum values?.

Reviewer 3 Report
The authors investigate the realization and manipulation of a two-dimension (2D) asymmetric electromagnetically induced grating (EIG) in a sample of Rydberg atoms exhibiting the van der Waals (vdW) interactions. In this system, they find by modulating the amplitude and frequency of the control field in a two-dimensional correlation, the probe field can exhibit an asymmetric diffraction pattern, and give a brief theoretical explanation.
I recommend this paper to be published after they will explain my concerns below:
1、 In Equation 11 on page 4, the absorption and dispersion coefficients are confused by the same letters as the phase representations in Equations 8 and 9, and it is recommended to use other letters instead.
2、 In the introduction of Figure 3 on page 5, each figure is not specified.
3、 In Figs. 4(a) to 4(b), no obvious change in diffraction order is seen as the modulation amplitude increases.
4、 There are several symbol mistakes in the manuscript, such as line 98 on page 5.
