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

Hi sir, I really appreciate your reply.

Thank you for your advice and solution. It is becoming crystal clear now.
Yes, I wanted to design/model power beam splitter on Silicon wafer with SiO2 buffer layer. For such design, is it better for me to use OptiFDTD instead of OptiBPM?

Hi sir, thank you for your reply

1. Yes. Even more, i can never make my own design however simple it is. The only model having acceptable simulation result is the ‘Getting Started’ demo model, if it’s designed in my PC it’s definitely going to be pixelated. I even tried to build exactly the same model as the ‘getting started’ demo and the result for my copy is pixelated while the demo model is just fine
2. 13.1.1.1467
3. I checked my windows update history and all i can see is the windows defender definition update, no significant update between the period
4. Sure.

I am looking forward for your reply.
