This lesson simulates the effect of anisotropy by considering a buried guide.

The core has an anisotropy relative permittivity tensor with components εxx   = εzz   = 2.31 and εyy   =  2.19 .

It is buried in a cladding and substrate of permittivity ε=  2.05 .

The procedures are:

•     Defining the materials

•     Defining the layout settings

•     Creating the linear waveguide

•     Creating the linear waveguide

•     Setting the simulation parameters – 3D Anisotropic tab

•     Viewing the elements of the permittivity (XY cut)

•     Calculating the mode

•     Computing the magnetic field

Before you start this lesson

•     Familiarize yourself with the procedures in Lesson 1: Getting Started.

•     Familiarize yourself with the procedures in Lesson 3: Create a single-bend device.
