A1: I personally recommend much larger, say 1um by 1um. But your seems ok.

A2: you can do it. But I would not strongly recomend it, since a pulse is faster and you can get the single frequency result. And since the shorter wavelength in the source is smaller than 630nm, the mesh would be finer, so more accurate. With faster simulation and more accurate result, an intituitive choice is pulse. You can set your monitor to record this wavelength only.

A3: You can use two analysis group. But with more familiar with script, you can use one such analysis group, with two linearly polarized sources, and pick up both Ey and Ez at the same time. I think this way may be better: your device has polarization effect, eg, a Ey incident light can induce both Ey and Ez. In experiment, you use circularly polarized source, not linearly polarized light, right? using one analysis group with two polarized source, it counts all the contributions.What you think?
