Hello,

Is there a more efficient method for comparing the reflectivity measured by monitors after conducting a sweep? The sweep altered the thickness of the material layer and affected the reflectivity measurements. I'm seeking a way to calculate the mean of the reflectivity of each simulation so I can better compare the data.

If not, I will need to download the text file and use excel to determine the means then compare. This will be very time consuming so I wonder if there is a better way for me to do this.

Thanks for your time and assistance,

Frederic Wu

In a sweep, you can get the mean value of the result:

Actually you can use getsweepresult sctipt comman to extract the data:

getsweepresult - Script command

then you can do more operation, such as mean:

mean - Script command

or any other post processing. To use the software efficiently, I would strongly suggest to learn more about the scripting.

I tried researching but since I do not actually understanding how to code in lumerical, could you provide me with some more guidance and maybe show me how my goal can be done?

Task clarification: So basically, I created a sweep function that changes the thickness of a material between a given range 48 times. After running the sweep function, I hope I can obtain the mean of the reflectivity measured in of these 48 times of simulations so I can see how changing the thickness affected the mean reflectivity.

Many thanks for your assistance, please provide me with some more guidance.

two methods have been suggested:

1: as shown in the sweep object, you can always use mean operation for all the sweep.

2: you can use getsweepresult.

in the getsweepresult page, you can learn some exmaples. For more informaiton, please refer to

https://optics.ansys.com/hc/en-us/categories/360001998954-Scripting-Language

you can watch vidoes, and learn each script command.

Please try to write script. if there is an error and you cannot fix it, please write a separate post.
