Hi Mr. Scott, thank you for your help and explanation. I really appreciate it and I definitely will learn more about this matter.
Anyway, I have one more question regarding your other product, OptiMode.
I tried to create a model that consists of 4 layers: Silicon, SiO2, and GaN with air as the cladding (see ‘Structure_error.png). But The OptiMode can never run the simulation. I believe the error is caused by the refractive index of silicon which is higher than all the layers in the model and so the OptiMode expects the silicon layer to be the desired waveguide which is not the case. I want the light to propagate in the GaN layer.
My question is: Is it possible to set the GaN layer to be the waveguide layer? I tried to look into the doc but couldn’t find any information
