I am using Lumerical FDTD software to simulate the coupling between a photonic crystal ring resonator and a photonic crystal waveguide. During the simulation, I encountered the following issues:

1. The size of the simulation region affects my results. How should I determine the appropriate simulation region size to ensure reliable results?

2. For photonic crystal device simulations, is it necessary to have an integer number of mesh cells per lattice constant to ensure identical mesh partitioning for each periodic unit?

3. The TE mode in slab photonic crystals is defined as having the electric field oscillating parallel to the plane of periodicity and the magnetic field with a component perpendicular to that plane. This seems different from the TE mode definition in waveguides. Can a TE mode source still excite the TE mode of the microcavity?
