How many FDE solver region can you have in one simulation file?
If a 2D FDE solver region is oriented in the XY plane, the solver will assume the direction of propagation is in the Z-direction. Is this statement true or false?
If a 2D FDE solver region is oriented in the XY plane, the solver will assume the structure is completely uniform in the Z-direction. In other words, there can not be any variation of the structure in the Z-direction. Is this statement true or false?
What properties can be set for the FDE solver region?
In which situation would you use the material fitting over a wavelength range?
By default, the FDE solver region sets a uniform mesh, but you can add a mesh override region to locally refine the mesh. Where would you add a mesh override to specify locally a smaller mesh?
You want to model a waveguide with no radiative loss. What boundary condition can you start your simulation with, to calculate all the modes?
How can using symmetry affect your simulation?
Open file FDE100_Solver_SOI_waveguide_Thermal.lms. This simulation includes an index perturbation material. Set the simulation temperature to 400K and calculate the modes at a wavelength of 1.5 um. What is the effective index of the fundamental TE mode?
Insert your answer as a number with three decimal places precision. For example, if the answer is 0.254912, type in 0.254.
Create a new project. Add a rectangle with an x span of 1000 nm and a y span of 500 nm. Set the refractive index to n = 3. Add a solver region that has an x span of 2000 nm and a y span of 2000 nm. Use metal boundary conditions and a mesh size of 25 nm in both the x and y directions. What is the effective index of the fundamental TE mode at wavelength 1.55 um?
Insert your answer as a number with three decimal places precision. For example, if the answer is 0.254912, type in 0.254.
The following image shows a Si waveguide on glass, with air on top. We want to use symmetry to reduce the simulation region. What type of boundary condition should we use to restrict the modes to TM (y-polarized) modes only? Where does this boundary condition should be applied?
