Hi Iqra,

Are you referring to surface rougness by any chance? If yes, this article may be of use to you: Tips for adding surface roughness to structures. If not, please feel free to add more details about your requirements.

Also, I will recommend posting your Lumerical (Photonics) related questions on the Photonics Channel of ALF.

Regards,
Amrita
