I appreciate your support and I will try optiBPM.

We implemented a matrial with a relative index of 1.59 and an index difference of 0.006.

It will do this just as you mentioned and I hope I can do.
Thank you so much for your valuable help and your time.

Dear Mr. Newman,

Your comments are great and I appreciate your attention.

You are right about propagation direction in the software.

By script engine do you mean “layout script”?

With layout script I have created periodic structures such as gratings as well as other components including observation points and input illuminations.

Do you mean that I should define a waveguide for each point of my structure with desired refractive index and then in the layout script, I arranged them in the locations to create the profile?

Can I change a refractive index of a grid point in my design with scripting directly without a predefined waveguide in the “PROFILES AND MATERIALS” section?

Dear Mr. Newman,

Thank you for your attention.
My structure, in general, is three dimensional, its cross section as you mentioned is in the x-z plane and propagation is along the y axis.

The problem is that I want to introduce anisotropic refractive indices along x and z directions. I need that along x axis, the refractive index to be a Gaussian profile and along z axis it has an exponential profile. Along propagation direction (y axis) the refractive index is a constant value.

So for clarification I would like to inform you that:
1- my design is 3D.
2- Cross section is in the x-z plane and propagation is along y axis.
3- I need a Gaussian refractive index profile along x axis and an exponential profile along z axis while along propagation direction (y axis) a constant refractive index must be set.

Thank you so much for your time.
