I am developing a 2D photonic crystal resonator and would like help from colleagues to configure the propagation of electromagnetic waves in the time domain using the wave optics module. Researching devices based on 2D photonic crystals simulated in comsol on the internet, I realized that there are few tutorials using this software. Can anyone tell me why?
I assume because this function is not why people pay a lot for COMSOL.
In any case, what do you expect to see in the time domain? Are you working with nonlinear optics?
If not, you can reconstruct the time domain propagation through a fourier transform over the steady-state results, and tweak it to your liking through the spectrum you define.
I'm working with linear optics and I want to study the transmission spectrum at the output of the four ports of the projected photonic device.
