at the moment I am simulating multimode interferometers using AlGaAs ridge waveguides. I need to do simulations being up to mm’s long. These take a very long time.
How can I accelerate these simulations?mmi3x3_1500um.fsp (3.5 MB)
Introducing symmetry boundary conditions is not always possible, changing the mesh size is not possible in 2 dimensions because of needed mode confinement.
The best workaround I have found until now is to do 2D simulations and verify the result in 3D, but the outcome is not always comparable.
The file I have uploaded is a(n) (rather extreme concerning simulation volume) example of the kind of simulations I am doing.
