Hello,
I am trying to simulate dielectric rods, using optiwave’s language they are defined as “True 3D cylinders”, these cylinders have the same radius from top and bottom. In real like, etch is not ideally anisotropic, there could be underetch or overetch as depicted in the figure I attached. I am trying to lay down the design for the latter two “imperfect” cases, but am struggling to do so.
When I try to edit the lattice parameters, I can change the radius and height, but I actually want to use a function to change the radius with the height, so its wider on one end compared to the other. Something like Radius=constant*Yposition, where Yposition is the vertical coordinates in my design, but the problem is accessing the “Yposition” information.
Does anyone have an idea what I could do in this case?
Thank you
Yameng
