To define the materials for the Anisotropic 3D Mode solver, perform the following procedure.

Step Action
1 In the Layout Designer, from the File menu, select New.

The Initial Properties dialog box appears.

2 Click Profiles And Materials.

The Profile Designer opens.

3 Under OptiBPM Designer 1, in the Materials folder, right-click the Dielectri folder and select New.

The Dielectric1 dialog box appears.

4 Click the 3D Anisotropic tab and deselect Use default.
5 Create the following dielectric material (see Figure 2):

Name: AnisoEps Permittivity tensor (Re) of the core:

εxx  = 2.31

εyy  = 2.19

εzz  = 2.31

εxy   = 0

6 Click Store.

The Dielectric material AnisoEps is saved in the Materials folder.

7 Create the following second dialectric material (see Figure 3):

Name: Eps Permittivity tensor (Re) of cladding and substrate:

εxx  = εyy  = εzz  = 2.05

εxy   = εyx   =  0

8 Click Store.
