Curved waveguide DBR
I am interested to simulate spiral DBRs as shown in the reference papers below. One has rectangular corrugation and the other has a circular post for pertuburation. Maximum propagation length is and total footprint is roughly 500µm x 500µm
My first impression is that EME is not the right option for this, but maybe initial simulations varFDTD and final with 3D FDTD will be the right way forward? Is there any other clever way to simulate such design?
