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